Your Stevens model 15A was produced from 1936-1945.
The stevens model 15 was made from 1936 until 1971.
The singleshot Stevens 15A and 15B .22 rifles are worth %50 to $150, depending on the condition. The higher-end price seems to keep them sitting around for quite a while.
The Stevens model 52b dates to the mod-1930s. Stevens is the same company as Savage, and also sold rifles under the name Springfield (not to be confused with the Springfield Armory military rifle maker) and shotguns under the name Fox. The model 52b was also sold by Montgomery Ward under the Wards house brand "Western Field" as a model 36. To confuse matters, Wards also sold the Mossberg model 10 (very similar to the 52b) as a Western Fields model 36.
It looks like it would, but you won't know unless you try.
These were made from 1936-1971.

Model 15 could have been used by a dozen manufacturers. Unless you know the name or the gun, you won't be able to find your answer. But if you only want to know what it is worth, go to Walmart or Gander Mountain and find the least expensive new .22 with a similar action (bolt, pump, semi-automatic, etc) and figure that yours is worth 1/2 to 2/3 of that price. Of course, if this happens to be something old and collectable (unlikely but possible) it could be worth more.
