A nice 1949 Crosman model 101 with all the 1949-specific trimmings.
The crinkle paint, the rear sight, the hammer knob, bolt retainer are all unique to guns produced in 1949.
1949 was a pivotal year for Crosman: lons of stuff going on with the introduction of CO2 guns, etc. It was also the last year of production for the model 101. Interesting that one of the most desirable 101 versions is this 1949 model. Pretty darn rare, too.
