The Magnum follower (not H&H) is used with what Winchester called the "short magnum cartridge" rifles (.264 Win Mag, .300 win Mag, .338 Win Mag, and .458 Win Mag - not to be confused with today's "WSM" and "WSSM" cartridges). This is an original Winchester part in excellent condition.
The pre-war followers have the top-side relief cut. Post-war followers do not have this feature.
We use the NRA Modern Gun Condition Standards Grading System for grading part conditions. You can read about it HERE
