I recently picked up a 4" model 10-5 that is stamped "U.S." on the back of the grip frame. I don't see any other unusual markings anywhere. Diamond insert grips are numbered to the gun. Serial number is C767XXX. I thought one of you guys might have something similar and give me a little more info on it. A friend told me he thought it might be some kind of pilot weapon used in Viet Nam but as of now there is no proof of that.
