I have a family member who brought me an interesting 38 Smith & Wesson the other day. She is wanting a ballpark value on it and I did not know what to tell him. It is 38 caliber and says U.S. Service on the barrell. It appears to be of an alloy of some type??? Her brother, my uncle, was in the Air Force in the early 50's. I thought it might have been his service weapon but cannot be sure. It has no model number on it. I read the Air Force issue would have Model 13 stamped on it but this has nothing. I do have a serial number. Gun appears to be in working condition and has been well cared for. Can anyone give me any info. I know pics would help but I have none at this time.
