Originally it sold for ( depending on the year ) $36.95. it was made between 1955-68.
The model 126.1930 was made by Crosman. It's really a Crosman model 140 made between 1955-68.
I don't believe that Crosman ever made a model 5100. (But I may be wrong.) I've searched all my catalogues and references and can not find any information on a model 5100. They did sell a model 6100, it's a Dianawerk model 45 from 1982-88. Check you numbers again.
About $140 (USD) on Amazon.com.
$1400 why are you selling it?
I would give Crosman a call. The stock is a custom part but I that will sell it outright see the link below...
Daisy, Crosman, Remington and Beeman
1200-1400 dollars if it is in good shape and runs good
Yes it's sold in Sporting good stores. It' the Crosman 357W. It sells for around $40-$50.
The Crosman 130 was made from 1955 to 1970. It is no longer on the market. The condition and demand determine the price you will pay. Anything Goes. However if you had one that was brand new and still in the box it would sell for around $85 today.
It would depend on the model that you're trying to sell.
200 bucks
The model sb-620A 20 GA. pump shotgun was a copy of the Winchester model 1400 and was manufactured by the Savage Arms Co. for Montgomery Wards stores from 1926-1945. In excellent condition (like new) this gun can sell for as much as $250, in good condition, as much as $175.
