What model and what condition is it in.
It all depends on the current condition of the Rifle.
My understanding is the model 938 was a toy rifle not a bb rifle, but I did find out it was made in 1988
This BB RIFLE not gun. Would be worth between $40-$50 in Good condition. It was made 1963-73
Around $45
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
Which model, what is the condition of the BB gun or is it a BB rifle..
Less than $50, typically.
I've gone through several air gun catalogues and have been unable to locate a Daisy model 170 bb gun that has ever been made. I did find a Daisy BB gun model 5170 and a BB rifle model 1170 along with a BB rifle model 107 but "NO" model 170. So here is what I suggest. Contact Daisy, They offer a service to evaluate older Daisy antiques for free. See the link below.
Nothing, unless you can tell me the model number, the current condition and if it is still working. Also is it a BB gun or BB rifle. Without more information it is not possible to answer your question.
It would be worth between $80 and $105 in good shape.
The Rifle was made between 1957-58. without more information about the condition of the rifle it is not possible to answer your question with an estimate of value.
