1970
What model?
100-5000 or so depending on EXACTLY what you have.
Revolver made by D Wesson chambered for 357 Magnum
No such revolver made by S&W
Smith and Wesson 500 magnum revolver
The value of a Smith and Wesson Model 51 22 Magnum Revolver would actually depend on a number of factors. Some of these factors would include the age and condition of the Revolver.
An N frame .357 Magnum revolver.
A Smith & Wesson .44 Magnum revolver.
With no more than that to go on, the best I can give you is a range of 300-3000
Rare is not the right word. It was a limited edition.
No. While Dan Wesson DID make a .44 Magnum revolver, it was not known as a Desert Eagle. IMI made a .44 magnum Desert Eagle Auto pistol, but not a revolver.
Between $150-250, depending on model, barrel, and condition. In my opinion, an excellent revolver that is underappreciated. Durable, reliable, and accurate.
