The John Browning's designed Winchester Model 1890 comes to mind.
1890s with serial # below 15k were solid frame (that is, the barrel and the magazine tube attached directly to the receiver). In 1893, a take down model was developed (also designated the 1890).
The second and later slide/pump action .22 of Winchester was the Model 1906. This differed from the 1890 in having a round 20" barrel and a composition buttplate.
Two other Winchester slide/pump actions were made: the hammerless Model 61 & external hammer Model 62.
I go blab on, but would like more details so as to the markings found on your gun as well as .
