In the 70's I bought a fresh 61 from my neighborhood friend for $40 (his dad had ditched the family leaving a nice firearms battery behind), and gave it to my dad for his birthday. Dad didn't blink that 13 year olds were engaging in the gun trade (he was a WWII vet), just smiled and thanked me. We shot it a bit.

When my dad died I got the .22 back and tracked down the old friend offering it back to him for a 45-year inflation adjusted price (about a third of then-current values). To this day it is one of the only things from his father he possesses.
