I just bought this escape compass in the US. It’s a type I had never seen before. It consists of a plexi glass dome and a metal base plate with a pin on which the arrow can rotate. The needle is made of stamped steel. The blued end points North. The needle is fixed to the pin with a brass cap. There are no markings anywhere. This type is said to be issued with American escape kits, but I have no documentation anywhere to support this. As far as I know the only type of survival kit the Americans had during WW2 was not issued in the ETO. If anyone knows more about this, or has one like this, please let me know.
