Anyone know of an idiot's guide to BEF Vehicle markings, Div signs etc? Masses of info for any other period of WW2 but the 1940 campaign seems neglected. I know 51st HD had either a stag's head NOT the famous HD sign. I know my mate had this book a few years ago. Maybe he still has it. I've found these for models but 4th Div and 51st Div are wrong.
