WINCHESTER MODEL 70 SUPER GRADE FEATHERWEIGHT Description
.243 Win., .270 Win., .30-06, or .308 Win. cal. only, because of inconsistencies of Super Grade action component jeweling (i.e., engine turning), a simple stock and hinged floorplate change can create an "instant" Super Grade Featherweight (check stock carefully for wood filling near area of Standard Super Grade rear sight "boss" in barrel channel), all Super Grade Featherweights have a raised cheekpiece with wraparound "fish tail" checkering, all have rust blued barrels, less than 1,000 mfg.
This is perhaps the rarest variation of the Pre-'64 Model 70 - beware of fakes.
