Who made Sears model?

Answer 1

High Standard, because High Standard was actually owned by Sears at the time, and JC Higgins was high executive at Sears that the series was named for. High Standard did not start putting out weapons in its own name until 1962. The model 66 was made until 1961. The 583.XXX beginning indicates made by High Standard. The last three numbers do not indicate year made, but which lot it came from, and the lot indicates year made. Mine reads one side - JC Higgins Model 66 Sears, Roebuck and Co. 583.608. and other side says Model 66 12 GA.
