Manufactured between 1933 and 1945.
The savage/stevens model 58 was made during the years 1933-1945.
The value of a Stevens 58b bolt action 410 gauge gun which is pre-1968 depends on its condition. This gun in excellent condition is valued between 40.00 and 100.00 as of 2014.
I just bought a 58b and found the magazine at numrich gun parts.

Started production in 1937 and continued to 1981's. The older models had plain stock(smooth) and the newer models had the checkered pattern on stock.
