Hello jmoore, the barrel is shortened to 20" and marked on the left side of the barrel with (30-30 WCF Switzerlandicon). The serial # on the barrel matches the reciever, it is indexed and has the cross stamped on the right side. I have never seen an original swiss 1889 so I don't know if the breech end was cut short and rechambered and rethreaded or a sleave soldered in. The front sight is a ramp with a military(mauser style) inverted v blade and the rear is a marbles style w/ elevator. This is the fifth 1889 30-30wcf sporter I've seen and they are all in a small town (Fort Frances, ON. Canadaicon) All five were identical, maybe a Winchester Canada/Cooey deal. Thanks Joel.
