I just picked up an octagonal 1890 winchester rifle barrel (only) at an antique store. From the stamping of 22 short on top near the threads I believe it is a first model. I thought it might be a candidate to be relined by someone restoring an old 1890 but when I measured it, it is coming up about ¾ inch short in length- as you can see it is “missing” in front of the front sight. Doesn’t look to be sawed off- possibly a factory job? My questions are- Why would someone shorten the barrel, and does anyone have any idea what the strange stampings are on the under side ? (see photos) I’m wondering if it’s an old gallery barrel that’s had the daylights shot out of it then replaced, or maybe something strange like a factory test barrel? Any ideas would be appreciated…
