If it's extremely difficlut or impossible to come up with components I think the price would be lower. .25 Stevens Rimfire is a good example. If its a centerfire and components are available and it's a cartridge I don't have a rifle for I am willing to pay a fair price for a good example. Sometimes you can get a deal on one of these. I got a Stevens 44 in .28-30 for what I considered a steal on Gunbroker a while back because of the odd chambering which I had been looking for.

You asked for a range ,

Market for that rifle is very small. At the low end as parts action 600 dollars rest of the parts another 300. Parted would sell fast. Collectors will pay if they want it won't if it's not right. Experienced collector will spot added vanish. I can't tell from the photos.  Appears to me it's as it left Stevens with normal use wear may not on actual examination. 900 dollars for fast sale to a dealer who has to make a profit on re sale. He will use parts price as a floor. On a table at a gun show frequented by single shot buyers agree with Marlinguy, 1300-1500 asking price.

Few shows that fit that discription. March Baltimore show one for sure, and understand the Oregon show is strong on single shots. Big Las Vegas show is focused on condition and high end, doubt it would sell there.

Add that one to the list. Thing about the shows if you don't have a table walking with the gun generally brings low offers, and you have the cost of attending.

Best way to sell a Stevens is right here . I have never gone wrong buying or selling on this forum.
