Recently picked up my 3rd S&W (and third USAF issued pistol) for the collection.
A lettered M39 manufactured in 1969, with box, paperwork, factory letter, spare mags, and USAF asset tag dated 1971.
From what I can gather these were from a small order by the Air Force for General Officer issue during the Vietnam era.
Pistol is stone mint- doesn't appear to have ever been fired. Looks real nice lined up next to its brothers the M13 lightweight and M15 both also Air Force stamped and factory lettered.
All thats missing to make the rig complete would be the original issue holster. Been doing some research trying to hunt one down. Have the correct holsters for the revolvers already.
