Any Stevens firearm that is marked J Stevens Arms and Tool co.Was produced between the years 1886-1915.That is as close as I can get.
Yes. I have one. It says Stevens right on the receiver.
The Model 215, a hammer gun, and the model 315, a hammerless
yes
Yes. Some are stamped Stevens by Savage Arms Co.
A gunsmith should be able to make replacements.
A long time ago. So long ago that no one knows.
All my records indicate that stevens did not make a model 337 shotgun.If your stevens shotgun is marked U337 under the receiver,this would be a serial number,not a model number.
1947 - 1953
1958 to 1965
I am not sure about the "Buckhorn" part, but if it is the same as the Stevens (part of Savage Arms) 52B S-L-LR .22 caliber single shot bolt rifle it should date to the mid-1930s. This firearm was also sold by Montgomery Ward as a Western Field model 36. (To make things confusing, the Western Field model 36 referred to both a rebranded Stevens model 52B-62-83N and a rebranded Mossberg model 10. The Mossberg 10 was made 1933-35.) The 1934 Stevens parts catalogue includes the Stevens model 52B (see http://www.cornellpubs.com/Templates/StevensParts1934.htm), as does the 1938 Stevens parts catalogue. The Stoeger 1939 World's Fair Issue Gun and Sports Catalogue does not include the 52B, but does list the Stevens Buckhorn models 53, 56, 66, and 76. The website www.e-gunparts.com lists the component parts of the Stevens model 52B under the heading "Savage, Fox, Springfield, and Stevens." All of these were brand names used by the Stevens company.
Unless "Johnson Stevens" is a Hollywood producer I've never heard of, I think you are asking about Hercules shotguns, not a movie. These were made by two companies, Iver JOHNSON Arms and Cycle Co and J. STEVENS Arms Co., from about 1935 until the late 1970s.
The Stevens/Savage M720 was produced from 1930-49 in various versions. M726-1931-49,M740C-1936-49. They also made an aluminum framed model(M745) from 1940-49.
