I inherited a 12 ga. single barrel shotgun with the name 'Nitro Marvel' engraved on the side. Other than a serial number and a patent date (Aug 17, 1896) there are no other markings whatsoever. A gun friend found in one of his books that it was manufactured by Crescent Fire Arms Co., and from there we have gotten nowhere. I would very much like some more information on the gun and the approximate value of it. I have been emailing another Nitro Marvel owner who has also hit a dead end in finding out anything about them. :| :? Can someone please help?
