Hi guys, thanks a lot, from what I can see there doesn't seem to be a hallmark around the lid or the rim but there is a number three stamped on the inside of the lid. There may have been a hallmark on the bottom of the pot at some point, but the bottom has been replaced in copper somewhere along the line. The 24th is of particular interest to myself, as it was the regiment of my local area back home, and it forms part of my own collection of medals. It was only on the off chance that this caught my eye while in an Oxfam charity shop in Surrey, and I couldn't leave it there!
