Aston Martin’s 1921 A3 – the only remaining prototype built by Robert Bamford and Lionel Martin – will be on show at Prescott Hill Climb from 3-4 August.
The car, which C&SC featured in April’s Aston Martin supplement, came to light at Bonhams’ 2002 Aston Martin Works sale and has since been subject to a full restoration.
The A3 will be joined by a line-up of historically significant pre-war Astons including Team Cars such as the Green Pea, which ran in the 1922 French Grand Prix, plus Brooklands stalwarts the Halford Special and the Razor Blade.
It is hoped all three will run competitively on the course alongside 250 examples of Vintage Sports-car Club pre-war cars.
Around 15 pre-1939 Bertelli Aston sports cars will also be on hand, including the only Renwick and Bertelli machine in existence, the 1926 Buzzbox.
The display will be located in the pre-war Orchard Car Park on 4 August, while the competing cars will be in the paddock all weekend.
Tickets are priced at £15 on Saturday and £25 on Sunday, with savings of up to £10 to be made by purchasing tickets in advance before 30 July, under-16s go free.
