1900 American Eagle Army Test Luger / The frame is the old model with the American Eagle seal over the chamber. The thumb safety is the Type II and is not marked but is polished and the extractor is the leaf type. The safety is the squeeze grip with the thumb safety "safe" in the up position. The Serial Number is 4 digits with no "Germany" marked export stamp. These models did not have a stock lug but do have a hold open.
