I've owned the Jap Wins and Brn. I would say they are better only from the standpoint of being made of modern steel. Nothing wrong with function or accuracy either. Never bought on new but all were hi condition. The last one I had was Win 1895, 405Win. Nice rifle and shot well. Only shot about 60rds and traded it off. It just didn't feel like a original 95, it's hard to explain.
Last 1886 I bid on was Light rifle 1/2 mag 90%+. When I saw it I bid on nothing until it came up, about half way into 250 Gun auction. I had to get off at $3500 and my paddle caught fire. It went north of $5k. Gun was 45/70.
The Brn 86s putt right along at $2k most shows I see them at. I never seen one that wasn't in hi condition. The guys who buy them take good care of them.
