This will not fit a model 12

The model 100 .30-30, if it's the one with the visible hammer, is a copy of the Winchester '94. It was probably made by Winchester. A Winchester '94 stock can be made to fit. If it's the hammerless model it's a copy of a Savage '99. A Savage '99 stock can be made to fit it. TexasCharley -- Post-64 Winchester Model 94 -- The Ted Williams/Sears Model 100 is a version of the Winchester Model 94 as made for Sears by Winchester. They originally had walnut-stained hardwood stocks. We can supply new walnut stocks to fit. sales@countrygunsmith.net

sorry, no it won't. the trigger guard and floor plate, the hole spacing, the recoil lug, barrel, and several other measurements are proprietary to either post or pre 64 70s.

No, Winchester 1400
Possilby, but, may need to be fitted.
No, it will not. Check this website for a 1400 stock and forearm. Under the description it specifically states that it will not fit the sears 300 model. http://www.midwestgunworks.com/page/mgwi/PROD/1400stocks/RAM14111
