This is an ORIGINAL STRIPPED Winchester SHORT carrier that fits the Winchester 1890 (also THE EARLY 1906 and model 62 pump .22 rifles). It handles only .22 SHORT bullets. The model 1890 is more common to have the short carrier but there are 1906 and 62s that were produced in the short only caliber. This is an original part. It is stripped and will need the carrier lever arm (wp19) carrier lever spring (wp30) carrier lever spring screw (wp61) carrier lever pin (p108).
