That may be tough since the tenile plastic stocks tended to break and there have been no aftermarket replacements. Try Gunparts Corp or Jack First.

According to the Blue Book, all Model 94's were made from 1926 to 1945.
Depends on who made itl.
5100 is the Stevens model number, not a serial. These were made c. 1931-1941. The plastic was called "tenite" and often broke.
Boyd's stocks on the net.
Go to Boyd''s Gun Stocks web site and check the type of receiver you have on the j. c. higgind. Then you can narrow the wearch. I am trying to re-do a Stevens 311 12 Gauge Stock foe a 20 gauge. It will bolt up, but not correctly. The receiver "dogs" are to big on the 12 gauge. Lobo Gris
