Maybe saying the obvious but if we look at the Stoeger catalog where they are selling both BSA’s and Crosman it becomes pretty obvious why BSA’s seem to be almost non existent here after the mid 1920’s and Crosman brings out their 101. Look at the price difference, the BSA more than 4 times the price of a 101. The Crosman looks like a rifle Americans are used to? And I have shot both recently the Crosman with an aperture only design gives my BSA a run for the money at my 60 foot target range. They were a no joke value at the time and sold at hardware stores not Stoeger only catalogs. And these early ones were some of the best they made. Below are both my 1920 examples I shoot regularly. The Crosman stock 1920 valves.
