Bristol 412 prototype: Zagato’s dramatic exit

Classic & Sports Car – Bristol 412: a British car in an Italian suit

Had things gone to plan, then the Bristol 412 wouldn’t exist at all.

In an alternative world, the successor to the Series 5 Bristol Type 411, the Type 600, would have been launched in 1973, a year that not only marked the 600th anniversary of the City of Bristol’s Royal Charter, but also coincided with Tony Crook taking full control of Bristol Cars.

Alas, after being struck by development delays, the 600 was launched in 1976 as the 603.

The Zagato-styled Bristol 412 was a shock to the system for conservative fans of the Filton marque

It was the first Bristol to be conceived and developed solely under Crook, following the firm’s founder Sir George White (the third baronet) taking early retirement after being embroiled in a serious road accident in 1969.

Crook’s direct association with Bristol started in 1960 after the company was sold by Bristol-Siddeley Engines Ltd.

Prior to that, Anthony Crook Motors had been one of several Bristol dealers.

In the White family archive, there is a draft of the 1960 Crook/White partnership agreement (which would establish Crook as the junior partner via a 60:40 shareholding split), with Crook’s own handwritten edits.

The Bristol 412 was a departure from the norm, but the marque’s trademark spare-wheel location remained

Because neither man is here to ask, these notes can either be interpreted as revealing Crook’s reluctance to run the company, or that he was content with concentrating on sales, leaving Sir George to manage the factory.

In 1965, Crook reorganised his business to reinvest in Bristol.

This included surrendering a number of his British concessions, which included Zagato (one that he had held since 1959).

After this investment he became the only Bristol distributor, with all cars being sold via Anthony Crook Motors.

This one-off Bristol 412 prototype tells the story of the model’s inception

Come 1973, when he was the sole owner, Anthony Crook Motors would be rebranded as Bristol Cars.

The traditional narrative suggests that the 412 happened because Bristol wanted to move into the large open-GT market.

The source of this? It might have been Crook because, as Jeff Marsh, the former workshop manager at the Patchway factory, remarks: “He was a good storyteller! It changed every time you spoke to him…”

Regardless of that fact, this view isn’t accurate. As Jeff explains: “The last 14 or 16 411 S5s were still sitting unsold in Chiswick – we couldn’t sell any.”

There’s plenty of body roll even at moderate speeds, but the Bristol 412 corners tidily enough

“On the drawing board was the 600, which [Crook] had already put back one year, and he needed a stop-gap because there was no way he could bring the 600 in quickly,” remembers Jeff.

“He’d had dealings with Zagato before, and they promised that he could get the car up and running straight away.”

Giuseppe Mittino, who styled the 412 during his time as Carrozzeria Ugo Zagato & Co’s chief designer, recalls little about the project, but he does remember the impetus: “There was only the idea to transform the production Bristol car into a convertible version.

“We made a new proposal for a car with a hard and canvas roof opening, like Lancia and BMW.”

In Milan, Crook and Dennis Sevier, the man who assisted Bristol chief designer Dudley Hobbs, were shocked by the 412’s original, 18ft-long design.

Once language difficulties had been overcome, however, its nose was shortened and modified so that it would fit into a typical UK garage.

Crook may have been satisfied with his 16ft 2½in restyle, but Hobbs was not; he described it as being: “[Like] two shoeboxes, one stuck on top of the other.”

The car pictured here is that original 412 prototype – chassis number 7716434Z, today owned by James Calladine – making it the first of the last Bristol models to be designed by Zagato.

James points out its unique features: “The front does have a different profile angle, the production cars are more raked at the front while this is more upright.

“There are other subtle differences in terms of the positioning of the fuel-filler cap – which is on top of the rear wing, rather than on the side – the spacing between the rear-wing profile and the feature line, the doors’ forward shutline angle, the smaller extent of the wheelarch lips.

“But there is nothing radically different.”

According to Giuseppe, chassis 7716434Z was the one and only prototype, a suggestion that is supported by Crook’s modus operandi.

Jeff remembers exactly what Bristol dispatched to Milan: “A 411 chassis with the bulkhead in, plus A- and B-pillars, wheelarches – all the superstructure beneath the body was there… When it came back, as far as I can remember, it got painted and came down to us.

“We put all the dash in with radio strapping, then the engine got taken out again – I can’t remember why.

“Mr Crook had us take the car down to the outer ring of Filton airfield. There were four of us pushing the car around, and there was a photographer on the side.

“We had to push it and then dive into a ditch, so that Mr Crook would look as if he was driving!”

The rope handle for the glovebox is very Bristol

“As far as I remember, we put the radiator in and the fitters strapped it down so that it looked like it was the right ride height – and it went to the 1975 Earls Court Motor Show,” Jeff recalls.

“Mr Crook then sold it! We had three weeks to finish it – and I’m not joking – but it hadn’t even been on the road.

“Anyway, it came back and we put the engine in, and we had to work hard to get the dashboard together… When the targa top was on you could still see daylight through the gaps!

“Gianni Zagato came over to see the finished article. They drove the car to London, it poured down and water came in everywhere,” chuckles Jeff.

“So for the next car, they did a load of modifications – but all the S1s leaked, there was so much work on those…”

‘I’ve quipped about the Bristol 412 in the past, but this undiluted prototype has made me an admirer’

While it is believed that 98 or 99 bodies were eventually assembled and painted at Zagato’s factory in Terrazzano – and subsequently modified by Bristol upon delivery – this car was the first of 60 Series 1, Series 2 and US-spec 412s.

The remaining bodies would evolve into the later Beaufighter and the unique Beaufort.

The decision for Bristol to re-enter the market for large, open-topped GTs – now with muscular, 6.6-litre Chrysler ‘B’ V8 power – was certainly astute.

Crook, with his salesman’s eye, must have seen the success of the V8 tourer sector – a broad niche that incorporated offerings as disparate as the Jensen Interceptor, Triumph Stag and Rolls-Royce Corniche.

The apparent shortening of the Italian design is fascinating.

On this prototype it is most obvious with the bonnet’s leading edge being defiantly vertical.

Where the production 412’s nose is raked, here it is unapologetically blunt and you can’t help but fall for its charm.

What the 18ft 412 originally looked like is open to speculation: if Giuseppe does remember, he is not saying a word – and all his drawings are apparently held in the Zagato archive.

Such pondering aside, the 412 clearly draws on two cars: the Lancia Beta Spider, mixed with a touch of stepped-flank detailing à la Range Rover.

Hobbs might have produced a few jolie laide designs – he was in the vicinity with the 406 to 409 models – but the 412 is arguably the most visually eccentric Bristol road car.

The history of chassis 7716434Z reveals that it was acquired on 1 July 1975 by Sir Robert McAlpine & Sons, wearing the numberplate MCA 111.

The 412 was later sold to Easter Tractors (Holdings) Ltd on 1 September 1978 – before being re-registered and/or changing hands five further times in 1981 (twice), ’94, ’95 and ’99.

The Bristol 412 prototype’s bluff nose is more pronounced than the production car’s

James has owned it since December 2002, by which time it had already had a colour change from its original red to black.

Both James’ father and grandfather owned Bristols, and he is a serial Filton owner whose first example was a 404 he bought as a teenager.

“Subsequently I’ve had a 405 drophead coupé, which is part of the reason I own this,” he says.

“I was taking part in a Bristol Owners’ Club tour to South Africa and I particularly wanted a convertible car to take on the trip.

“It was a ludicrous decision, and foolishly I sent the 405 for an express restoration, in the hope that I could have it done in time for the tour – but it wasn’t even remotely ready!”

“So I found myself needing a convertible Bristol,” he continues.

“I’d always hankered after a 412, and there were two or three on the market at the time when I found this car.

“The fact that it was the prototype made it tempting, so I bought it and had a great time.

“I enjoyed driving it so much more than I did my 404, that I didn’t sell it when I got back.

“Instead I sold the 404 – which, again, in terms of timing couldn’t have been worse: I don’t even want to admit how little I got for it!”

The Bristol 412 is arguably the marque’s most distinctive model

“I’ve kept the 412 ever since and it had a ground-up restoration from January 2008 to September 2012 with Andrew Mitchell at Mitchell Motors,” adds James.

“It had more than 1000 man-hours on the chassis and body before a drop of paint went on. It was quite rotten…”

The 412 is not conventionally pretty, but, given that it’s regarded as something of an entry-level Bristol, many examples lurk on the questionable side of shabby chic.

I’ll confess that I’ve quipped about the 412 in the past, but this undiluted prototype, with its glinting roll-over protection and alloy Avon Safety Wheels, has turned me into a genuine admirer.

Its sublime condition and colour combination elevate its desirability – and the warm sunshine does the rest.

This Bristol’s cheerful interior is spacious and comfortable

Inside, all is familiarly Bristol.

The blend of understated gunmetal paint and bright mustard-yellow leather gives it a cheeky wink of hip rebellion, like the vivid lining of a Paul Smith suit.

Roof panel off, rear hood down – the work of seconds – and the 412 is superb.

The effortless urge of the V8 suits the smooth Torqueflite automatic ’box, while the generous sidewalls of the 215/70 VR15s give a ride that ignores most road imperfections.

There is the odd shiver transmitted through the steering column (production 412s had additional chassis strengthening), but the power-assisted ZF steering is light and nicely geared.

It feels a trifle vague at the straight ahead, but it does make the keen front end do its bidding – impressing more than many luxury GTs of its era.

Sharp inputs generate immediate responses from the nose, then comes oodles of roll, even at low speeds.

Joining the Fosse Way from a standing start, and with the throttle pinned open it feels like hitching a ride on a tidal wave.

Your ears bathe in the signature offbeat V8 burble.

The strict horizontal location of that live rear axle, which never tramps about, means you are punted up to traffic speed in little time and with even less drama.

The 412 then cruises as easily and as lazily as this wonderful summer afternoon. The brakes could be better, but you make allowances and, anyway, what’s the rush?

At 60mph, with a mere 1800-1900rpm spooling away, this svelte GT epitomises reassurance and relaxation.

You savour the world rushing past as the velveteen V8 murmurs and your hair is tousled by the warm breeze.

The Bristol 412 is still long, even though the prototype was trimmed by 1½ft

Among marque devotees, Tony Crook is very much like the 412 – both remain divisive, attracting supporters and critics.

Certainly, working for him could make life far from a piece of cake – most of Bristol’s designers did not survive the 603’s development and Hobbs decided to retire in 1977.

But, as Jeff says: “I can’t knock him because he kept me in work for 25 years. Don’t get me wrong, he was harsh; but he was fair. I liked Crook.”

A stop-gap model the 412 may ultimately have been, but the classic world is a far more interesting place thanks to its unmistakable and unconventional presence. Especially so on a gloriously sunny day.
