Steve, I came across this info on a search. My rifle is consistent with the 3rd description ('30-'50). What's confusing to me is that the stock looks more like elm & not hardwood. Any ideas?Model 101 Pneumatic pump, .22 cal., single shot. Die cast receiver w/logo: pat. Oct. 28, 1924, Crosman Arms Co. Rochester, NY Rifle 1925-1929 Model 101 variant with applied logo and "clickless" forearm Rifle 1938-1939 Model 101 "Pellet" logo variant with hardwood stock & forearm. Rifle 1930-1950 Model 101 Late variant with crinkle finish paint and American elm stock Rifle 1949-1950
