This type of question is very hard to answer. If I asked you how much is my 57 Ford worth the first thing you would ask is. What condition is it in, is it still working. Is it is Poor, Fair, Good, Very good or Excellent condition. The same thing goes for rifles and pistols. You need to state the condition and if it still is working. Without that information it is not possible to give you an estimate of value.
Your rifle was made between 1976 to 1983
What condition is it in. That determines the value
there are over 100 different model Crosman airguns. You need to specify the model and the condition of the Crosman you want to know about
What model is it. How old is it, what condition is it in, is it still working?
It would be worth somewhere between $35 -$55
I can not find a CROSMAN model 350 BB gun, Do you mean a V350 BB rifle. If so then one in good condition is worth between $55-$70
As far as I know the Crosman Phantom is not a BB gun but a pellet rifle. If you want to see the parts list for the rifle then see the Crosman link below.
Model 454 Mfg 1972-82. Crosman no longer repairs this model but you can search the web under "Air Gun repair" and find a location near you to repair it. However remember that this gun in PERFECT condition is only worth about $50 at best.
Are you talking about a Gun or a Rifle? Please post the question again, except this time please add the model number, you will find it on the barrel. As far as I know Daisy doesn't make a 2006 10 pump BB Gun. They do make several single pump air rifles. However Crosman does make a multi pump Air gun, the Crosman American Classic. It this what you are asking?
Crosman offers a service to locate air gun repair shops that service older Crosman air guns. See the link below.
Both Daisy and Crosman air guns made BB guns for Sears. you will have to state the model to get an estimate of the value. Check the model number on the gun, any model that begins with 126 was made by Crosman air gun and any model that begins with 799 was made by Daisy air gun.
Crosman doesn't make the Grizzly, Daisy does. $40
it would be worth somewhere around $45. Source Bluebook of air guns 9th edition.
