The first photo is an AC four-cylinder that resided in Rhodesia (now Zimbabwe) up to the 1960’s. Another photo, same car below. Not sure what happened to it subsequently. The colour scheme of cream-and-black was quite popular and a couple of vintage cars still carry this combination. The family had a Morris and Austin dealership in Bulawayo and the father and son raced cars. They owned also a couple of Aces, an Aceca and a Greyhound,. Exporting from Zimbabwe had its own difficulties but some cars were successfully removed to South Africa. A 1930’s AC and the two Aces got away (one, MSV 512, still racing?) but no news on the vintage car. I believe some went then further, and on to Australia where the family settled. This car might just might be one of the those recorded from South Africa or Australia?
The second is an excellent period photo, taken by Bill Brunell, well-known photographer of the 1920-30’s who accompanied Victor Bruce on the Monte Carlo Rally. It shows an AC open-tourer on the Brighton and Hove Motor Club Trial, probably 1924 or 1925. The number plate identifies it being a local car, registered in West Sussex, so the lady competitor was likely a club member.
