This Super Grade configuration combines classic Winchester styling with practical field features. The blued steel barrel is 22 inches long and paired with a hooded ramp front sight and a barrel-mounted open rear sight. A banded front sling swivel complements a rear swivel stud in the buttstock, maintaining a clean, purpose-built layout for a heavy-caliber sporting rifle.
The walnut Monte Carlo stock shows premium Super Grade touches including hand-cut checkering, two cross-bolts with rosette escutcheons, and an inletted stock oval. A black ventilated "WINCHESTER" recoil pad and a 13.25-inch length of pull support comfortable shooting with the .458 Win. Mag. chambering.
The action is the post-64 push-feed design with a manual safety at the right rear of the receiver marked "FIRE." The internal box magazine uses a hinged floorplate, and the floorplate itself is marked "SUPER GRADE" in gold. Capacity is 3+1. The receiver is drilled and tapped and currently fitted with filler screws.
Additional factory-style details include the engine-turned (jeweled) bolt body and "WINCHESTER PROOF STEEL" barrel rollmark. The rifle is marked "Made in New Haven, Conn., U.S.A.," aligning with its 1975 manufacture date during the 1970s production era.
