Winchester Model 1910 "Self-Loading", .401 cal. semi-auto carbine.   Serial #8952, mfg. 1912.  Good condition.  An early law enforcement carbine that was famous for busting engine blocks and penetrating in and getting the "bad guys". A big boomer! 20” barrel has excellent bore, gold post front sight, open rear, 90% blue with crisp address markings.  Receiver has 60% thinning blue with fine surface corrosion.  Stock and forearm have very good original finish with few light handling marks.  Action works fine.  Babe Ruth’s favorite deer rifle - rarely seen!  C&R OK.
