This is the Carrier for 1890 Winchester LONG .22 pump action rifle. This carrier is SPECIFIC .22 LONG bullet (which are different than the LR). This is the part that brings the cartridge from the magazine tube into the chamber. The model 1890 design on this carrier is why it only takes one length of .22 cartridge. The LONG carrier lacks the removable cartridge stop on the Forearm like the later 1906 and 62 carriers (part number 542aORIG). The carriers we sell are original parts and condition vary. They are stripped and will need the carrier lever spring (wp30) and screw (wp61) the carrier lever (wp19A) and pin (p108)
