The Model 101 S/R Boar combines a 12-gauge top barrel with a 7x57mm Mauser rifle barrel below, providing a versatile two-shot, break-action layout. It uses a single trigger with a tang safety and has 25 inch barrels. The 12-gauge barrel is chambered for 3 inch shells, and overall capacity is 2 rounds.
This S/R Boar is an uncommon 101-based combination variant that uses the rimless 7x57mm Mauser rather than the more typical rimmed 7x57R. The barrels are marked with Winchester’s East Alton, Illinois stamp and “Made in Japan,” and the S/R rollmark denotes the shotgun/rifle configuration.
The coin-finished steel receiver features factory game scene engraving, with a running boar on one side and upland birds on the other. The solid, non-vented rib is configured for iron sights and scope bases, and this example has a scope mount installed.
The stock is high-gloss walnut with a pistol grip and shadow-line cheekpiece. Fine cut checkering, sling swivel studs, and a rubber butt pad round out the field-ready furniture. Length of pull measures 14.0 inches.
Proofs and markings include “WINCHESTER – S/R – 12GA – 3 in – 7x57 MAUSER – EAST ALTON ILL. U.S.A.” and “MADE IN JAPAN.” The receiver and frame are steel with a coin finish consistent with this series.
