Your Stevens Model 820B in 80% condition would probably fetch $80.00 to $100.00 at the right time. Most of the Stevens 22 calibers and shotguns were considered utility guns and do not hold a great attraction for the serious collector. They are a fine product with a long and proud history. Hang on to your J. Stevens Arms and Tool Co. firearms. They will serve you well and when they need repairs the parts are available widely and at very reasonable cost.
Go to gunbrokers.com and do a search, it all depends on the condition of the bluing and wood.
I bought one in decent condition a few days ago for $100. The stock was in good condition, the receiver needed bluing touchup, and the triggerguard needed buffed and reblued
slow rust bluing, best done by a pro...Get a copy of 'shotgun news' at a major book store for gunsmiths that do that type of bluing...LC Smith shotguns are collectible...
The Sears Ranger 12 gauge model 102.25 was made by Stevens Arms Company and designed by Browning. 100% grade would put the value at approx. $200.00 if it was a Stevens. Less to some buyers if they are not attracted to the Sears marketing of the same gun. I personally think you would be safe at $150.00 for a nice used gun that has most of the bluing and the wood is in good condition. These guns are very trustworthy and are very dependable. A real shooters shotgun.
Regular style...plain wood stock...bluing etc....anywhere from 25 bucks to 175-200 bucks. It's all about condition.
AMOUT OF BLUING WORN OFF, CRACKS IN THE WOOD ETC. $250 IF IN GOOD CONDITION
250 USD
Condition, condition, condition. Little Scouts (Model 14-1/2) bring between $75 for rough little guns to as much as $500 for ones with good bluing, bore and case colors. Usual on-line auction prices are between $125 and $200.
The collector value can only be assessed by a visual inspection & evaluation. Old Winchesters are very much like old classic automobiles... the graded condition and factory originality are the key factors in determining what they are truly worth.
your winchester model 1894 pre-64 rifle is valued at between 500-600 dollars for a rifle in the condition that you describe.
anywhere from $250 to $1200. a mildly used shotgun like the model 12 with no scratches and very good bluing that has a clean barrel would fetch about $$800.
it would depend on the condition of the gun ,the bluing the wood,the inside of the barrel the length, choke, functioning. a lot of variables. you could take it to several gunshows and see what they offer you and it would be worth some more than they offer you..
