I bought this mug, along with two others for £15, as it was dated 1945. British enamel mugs are quite a scarce bit of kit, I guess due to the fact that they could be easily damaged, as this mug is. I noticed that it had a code beneath the date which looked like an Air Ministry code and on checking I found that “21” is the code for “barrack equipment” and “21C” is the code for “metalware”.
I can’t find any other information on RAF / Air Ministry enamel mugs so can only assume that it is quite a rare item
