No such model. Winchester did not make a 'Model 1901 single shot .22 pump-action rifle.' They made a Model 1900, Model 1902 and Model 1904, which were all single-shot bolt-action rifles, and they made the Model 1890 and Model 1906 which were slide-action rifles but had tubular magazines. How exactly is your rifle marked? sales@countrygunsmith.net
