pre 1930 101, notice the small hammer plug and tomb stone peep sight.
This is a somewhat rare Premier-marked gun.



1938/39 102 clickless model,walnut stock, rubber fore-arm,
knurled hammer typical of the pre-war 102s, case hardened breech cover




early fore arm pre 1930, rounded and tapered at the front


valve stems- early thin stem with conical seal on the left, typical later stem with flat seal on the right


pumpheads- early head with leather rings on top, standard later Crosman head with urethane cup on bottom


bolts- 4 different bolts shown, early .22 with knurled handle,
later solid .22 with round knob, later .22 flow through bolt, .177 bolt


wood types- three different kinds of wood shown, American Elm on a late 40s crinkle finish gun,
walnut on a late 30s 102, and maple on a late 40s high-comb 102


10 different rifles, 100s, 101s, 102s, and a CG.
Here you can see the large 5-ring hammer on many of the guns and the diablo knob on the crinkle finish gun and the CG.


102 late 1940s with flame maple high comb stock



My preference is the 102, just because the magazine loading feature is so much easier. Power is the same, mid 600s at 10 pumps for a typical 101/102.
