I wonder if there are any information about early BMW motorcycles like type R 5 or R 51 being raced at Brooklands. Somewhere I saw some photos from Brooklands 1938 with such bikes. Rider names included ? Tisdall and also Francis Beart.
There have been riders on such bikes at the TT and/or MGP in 1937 (Worsick), 1938 (Cannell, Worsick) and 1939 (Reid)
Any help in getting more details is highly appreciated. Thank you.
