One of just 169 AC Aceca-Bristols is expected to make £55-65,000 at H and H’s 24 July sale despite no longer having its original engine.
Dispatched new to the Castle Garage on 15 January 1957, the car was then fitted with twin fuel fillers and competed in the RAC Rally the following year with owner DG Bennett.
Now powered by a Ford Zephyr MkII 2.6-litre engine, which was fitted before entering its previous ownership in 1998.
Overhauled in 2010 the engine comes complete with a fast-road camshaft, ported head, lightweight Volvo pistons and new bearings. The unit drives through a Ford five-speed gearbox, balanced propshaft and refurbished differential.
WTG 339 has been extensively restored with work including refurbishment of its aluminium bodywork, a retrimmed interior and fresh brightwork.
Also enticing is a 1966 Marcos Mini that has covered just 150 miles and is estimated to make £12-14,000.
