Does anyone have any information on the date lettering in BSA 'flat spanner' tools / spanners ? Or a reference list of the tools available. I have a spanner type that I can not identify at the moment.

Thanks. The tool I have is 'K' so 1939. Just need to find out what it was for now !

I have not seen it associated with any motorcycles, but I have seen it associated more with para bicycles... its the bottom one in this image.
But if it is '39 dated I dont think that could be associated with the para bike as it would be too early for that ?

I think its a bicycle spanner, BSA made thousands of them every year, it could be correct for an Infantry Bicycle Mk5 or Mk5*
