It depends on the particular model. Savage/Stevens/Springfield used the same designs, and a couple models were marketed by High Standard, some were sold under various 'store brand names' - JC Higgins, Westernfield, etc.
Best thing is to check the various 'house brand conversion' lists:
House Brand Conversion Store Brand to Manufacturer Cross Reference | Numrich Gun Parts Corp. | e-GunParts.com
