Garrell has sent me two rather poor photos of his Navy Luger, which appears to be a 1906 1st altered. He tells me that the frame is numbered #6377, the barrel #6476, and the take-down and side-plate #32. Because of his unfortunate disability, he is reluctant to try field stripping the gun, so we won't know if the receiver is numbered to the barrel, which is usually the case. He is thinking of offering on the Navy and the Colt in the photos, and wonders whether the Navy is worth $500.00. I told him that , despite it's poor condition and the mismatched parts, it's worth at least twice as much. Opinions, anyone? Regards, Norm
