Stevens 5100 was manufactured from 1931 until 1941
The model 5100 Stevens shotgun has a plastic stock
It won't have one since Stevens didn't serialize their inexpensive shotguns until the GCA of 1968 required it and the 5100 was made c. 1931-1941.
I would go to Numrich gun parts corp.They may be found on the web.
1941-1948, It then changed to model 311
Between 1931 and 1941.
The model designation was changed to 311 about 1941. Some were marked with both model numbers during the change.
Most likely Stevens they did make a model #5100
$150-$350 depending on condition. sales@countrygunsmith.net

The Model 311 is essentially the same as the Model 5100 which was identical to the Model 5000 which was really no different than the double barrel shotguns being produced by Crescent Fire Arms before that company was bought by Stevens.
