My mother recently gave me a model 36 that she said she purchased in the mid 1960's. It looks unfired, but she thinks she shot it one time when she first got it. It is in the old blue box and is still wrapped in the brown waxed paper it came in . It has the papers and a cleaning rod. The serial # is j76xxx. I know very little about gun values, and would appreciate any help and information anyone could provide.
