No serial numbers on these guns- all were made by High-Standard from about 1946 to 1960- the first three numbers are 583- which was Sears store code for a shotgun made by High-Standard (in which they owned a 65% controlling $ interest then)--the suffix after the 583 is the key- mine is an early one 583.1-- from that series until 583.12 A-Ok, from 583.13 to 583.22 apparently the retaining machine screw that keeps the bolt in battery in the receiver had some heat treatment issues-
Back then a shooter with the shotgun shouldered fired a shot, jerked the bolt to cycle the action, the bolt lug sheared and he pulled the bolt back into his eye glasses- the force of the shell detonating in the chamber did not cause the bolt to move rearward however- Sears and their Phila lawyers did a CYA and recalled them, vis a vis buying back the bolts, initially at $160.00 a copy- later at a $50.00 Sears gife card (smart marketing move, as you could only use it to buy mdse. from Sears at their mark-up)--
Howsomever- as the 16 and 20 gauge J.C. Higgins 583 series (there are some listed on G.I. auction site under American Shotguns at $150.00 each) did not seem to have any problem- as HS used the same billet to machine all three gauges- so the initial wall thickness and the finished wall thickness on a 20 gauge J.C. Higgins was great- nominally the difference between the breech dia. of a 12 gauge and that of a 20 gauge-
I have done the initial stock R&R (repair and reinforcing) will re-assemble it and off to the gun club range and the lead sled for the "proof testing"- I will Loc-tite that screw into the threaded hole in the receiver- you betcha--ya!!!
Thanks for the input- i did a Google
