Wow great rifle, I to really like the shorter barrel (are you sure that's factory ?) I have a few like yours (much worse) that I'm getting back on there feet, almost none have original barrels or sights, some have dust covers missing & holes drilled in the actions for scope mounts !

Most of these I could have bought complete for less than it has cost me to get them back to original !
Sort of like paying them off this way LoL .

If your barrel is good you are very lucky, if your magazine does not have engraving on the bottom it is most likely a replacement (normally have a Carbine type mag but some have the rifle type) & I would be very surprised (astounded really) if the rifle has not been refinished !

Some thing that really sticks out is the Winchester grip cap, same as my Win Mod 88 & Mod 100 had .

Great rifle & wish any of my old girls were as nice !
