The Pioneer Model 23 .22 rifle sold by Gamble Stores Incorporated is equivalent to the Stevens Model 52B. Savage/Stevens produced several firearms that were sold through dept. stores that put their brand name on them. You can find gun parts for it through Numrich Gun Parts Corp @ e-gunparts.com. Look for the Stevens 52B, the majority of parts are sold out. The gun would have been produced in the mid-30's. Hope this helps.
Its basically a Stevens 94B, just sold under Pioneer. I actually got one myself. They are the JcPenny version of Stevens if i am not mistaken. Worth about 150-300 bucks. But normally more towards 150.

I have a "Pioneer Model 26 Gamble Stores Incorporated" bolt action 22 rifle. It belonged to my father. He's 87 now - he bought it new when he was 12 in Deadwood, South Dakota. Hope that gives you some timeline. Mine is now 65 years old.
