These contract plates were created so that when a vehicle was taken into a workshop for repair the fitters could identify which spares list to work from, C7287 is the contract number, 24 is the 24th BSA contract.
Despite all the M20 parts I've had, plus a few bikes, I've yet to get an original come my way...:grimacing: ...It doesn't seem right!...:laughing: ...Ian
Same here Ian, my WM20 is from this contract and does not have the plate, but it does have a rebuild plate dated 4th April 1944 which is nice provenance.
