US1115.)WORLD WAR TWO US ARMY ARMOR OFFICER'S COLLAR DEVICES: super-attractive matched pair of burnished gold on brass. Reverse of each shows that characteristic 'snow flake' design. Clutch-backs that are marked with maker 'AMCRAFT, ATTLEBORO, MASS.'. Marked too with 'Acid Test'. These are still mounted to a really old collector's card with typed label 'TANK CORPS, OFFICER'S COLLAR'. Hyper-desirable matched pair. EXC++++
