I inherited a Model 48 22 Mag. It's in really nice shape except for thee tiny rust spots. Left and right tip of barrel, approx 1/4", and under right grip. Looks new except for those areas. Very faint cylinder line. My father bought new. He only shot a couple times and then it went in his safe to this day.
