I have a trench art round, from my grandparents. My grandfather never went to europe during WW11. Appears to be about 20mm. It has palm trees on it and comes apart with the bottom half being a lighter. The base is kind of dinged up but has a "36", 2 "stars" and "BPD", stamped on it. It is a belted case. Any idea what it originally started life as? Sorry I don't have any pics of it to upload.
Thanks. John
Less likely but possibly a .55 (14mm) Boys round? Marine Raider battalions were issued Boys Anti Tank Rifles so one with a palm tree is not out of the question.
