BSA M20 Motorbike markings (Arty) - ID required
 

Hi All

I have been sent some markings on a WW2 Guards Armoured Div BSA M20 Motorcycle.

Does anyone recognize the "Y" marking on the front mud guard?

The "H" marking is for the 3rd Bty Command Post I think.

Sadly the petrol tank is long gone.... so no service number etc.

Just found :) .... I didnt realise that it was on here prior.

That Y marking is the key here I think. It is Guards Amd.... but the Y marking on the shield could be regiment specific me thinks.
