SN: 852485B. 1950’s vintage .22LR with a 23″ barrel. Rare factory “parts cleanup” variant made using leftover model 1890 receivers. The serial range is at the end of the 1890 model and has a “B” suffix, correct for this variant. The metal has about 85% original blue with wear mostly on the grip tangs. The wood is very good with some marks and wear. According to Schwing, only 362 of these leftover parts guns were made. An interesting and historical Winchester rifle.
