John,
Good question, I understand from Brian Whittaker (Barbon archivist) Trevor Wilkinson entered a 1200cc TVR at Barbon May 1953. The first article in Autosport on the TVR Sports Saloon prototype is 6th August 1954.
Photographs in Filby's book show the first prototype EFV 748 was completed in 1949 this appears to have a bonnet badge it may say TVR but the photo is not that clear. It is reported by Filby that a local enthusiast bought the 2nd car just as a rolling chassis but Les Dale also completed the body work (Les completed the bodywork for the first three cars). This is supposed to have been completed Mid 1950. I guess this car may not have been called a TVR. Trevor Wilkinson was a member of Blackpool and Fylde Car Club and he is supposed to have competed in local sprints / hillclimbs in the 3rd car 1952/3. It would be good to find programmes / entry lists to confirm.
Stephen W has confirmed the only entry at Altcar in 1950 with 1172cc engine is F Pinckney Harrison in a FHN Special in the racing car class. The first TVR's are cycle wing 2 seat sports cars so unless the wings were taken off I wouldn't have thought they would be classed as racing cars. Does anyone know anything about Pinckney Harrison.
Edit I've just found a post saying Frank Harrison built the FHN from a GN chassis so not the car I'm looking for.
