The Romans
With such a detailed description of your shotgun, all I can say is that Sears sold shotguns, including .410 gauge, from the 1880's to about 1990.
I have a double barrel 20ga 101.7 eastern arms what is it worth
Shotguns sold by Sears through years were made by many different manufacturers. It is very difficult to determine value because of the many variables.
At least 20 years.
what is the model 101.7 in 20 gauge worth
Tell us a little more. Sears sold a lot of different shotguns and a serial number will not identify it.
It is a 410 Gauge, Bolt Action Shotgun sold by Sears. Mine holds one shell in the chamber and five in the tube. The book says that this is a Stevens Mod 39
Your shotgun was made by High standard in 1960 for Sears. The model 21 was first introduced by Sears in the spring of 1958.
A 1953 JC Higgins shotgun 12 gauge model 20 pump is values at about $150. It was sold by Sears Roebuck.
Sears mail order sold it. They were manufactured by Savage.
The JC Higgins bolt action shotgun had many "models" they just changed the last digits: 583.xx. This shotgun was actually sold back in the 1950's by Sears. The Sears company itself actually made the shotgun and then sold it in its stores. The name of the company was Sears Roebuck, but Sears actually bought out a company called High Standard Fire Arms to manufacture the gun. In the 1980's and 1990's there was a recall of the shotgun because the bolt on the gun was deemed dangerous because the screw that held the bolt in place became loose after discharge and could eject itself at the person pulling the trigger. From what I've seen on most auction sites, this shotgun in prestine condition has sold for upto $ 150, and in good or normal wear and tear condition it has sold for as little as $20-40 .
