This photograph dated November 1961 shows two Alpines which were driven by Sir Stirling Moss OBE & Jack Brabham who is leaning on No. 7.
Sponsors of the cars may have been by local dealers Bud Rose and or Larry Read.

A new colour picture of the 1961 Sunbeam works cars has just surfaced and is re-writing history. For years we in the States have assumed the works cars for 1961 were in the official Rootes livery of Seacrest Green (just like they were in 1962) with white hardtops.
But as you'll see in the attached photograph, they really were Wedgewood Blue. Two were right hand drive and the third left hand drive. In the foreground you'll spot one of each, with the other RHD car way up ahead. Picture from Scott Christie SAOCA.

Is that a Sunbeam Rapier parked outside?

Original photograph from Gerald Francis.

This photo from the early '60s was one of Rootes promotional shots for the American Market.

The only information we have about this one is what you see on the picture.

This Series III Alpine is racing alongside GT40s is from 1966. The race is the 24 hour Daytona and the drivers were, Donna Mimes/Suzy Dietrich/Janet Cuthrie.

Followed by Brabham.

Jim Latimer driving a factory prepared car. It would seem there is no filler cap but the race prepared cars had the filler cap run out of the back window.

No 78, a Series IV or V, was the one raced by Smokey Drolett and Rosemary Smith
