This BSA photograph was spotted by Marc Farmer at a Grass Track meet, and following a request for help in identifying it, Bryan Lambert was quick to respond .....

.....no problem here , the BSA is David Burgess' 1930-ish 500cc Sloper . It is a very special piece of kit , revised bore and stroke , special cams etc & pretty dam' quick as Marc will presumably know by now .

Thanks for helping us on this one Bryan.
