The Winchester Model 1890 is a pump-action rifle that was produced from 1890 to 1932, designed primarily for .22 caliber cartridges, including .22 short, .22 long, and .22 long rifle. The octagon barrel variant is considered more desirable among collectors. The serial number SER 312653 suggests that your specific rifle was manufactured in the early 20th century, around the late 1910s to early 1920s. Due to its limitations to .22 short rimfire cartridges, it may indicate modifications or specific usage preferences, as many Model 1890s were capable of firing multiple .22 cartridge types.
