There are two, which both departed my possession in the mid-1980's in order to finance post graduate education:
The Browning High Power that saved my bacon in Tierra Amarilla, NM one afternoon in 1979. I didn't have to fire a shot, but I truly believe that if I was not carrying that pistol and had not drawn it, that I would not be alive to post this today.
A pristine Colt 1908 .380 with original box, instructions, factory target, and factory hang tag. In addition to being a beauty, it was the handgun that my daughter fired at age 4 under my careful supervision.
I don't regret getting that Master's Degree, but in retrospect I wish that I had taken on a 2nd job to cover the additional expenses those two semesters.
