Years ago, I bought a unfired Model 52-2 from a life long friend, who'd bought it as a novelty
from another guy who'd bought it as a novelty and neither of them ever fired it.
I kept it a few years and shot it several hundred times.
All factory original: It feels like everything in it is running on ball bearings and has a 1 1/2 pound trigger.
(This thing is so accurate, Stevie Wonder could hold a 2" group with it.)
Several years ago, I thought I was more or less done shooting.
In thinning out the safe, I sold it back to my friend, who never fired it after that either.
A couple years ago, I got back into loading & shooting, made the best deal I could-
and yesterday--- the Model 52 is back home.
Life is good, and I'm happier than a dog with a new stick.
