Thanks! 

I *have* been very fortunate in finding them. I found all three locally. The 1894 action I bought as a sporter and got the stock and hardware from Tom.

The 1912-16 was my first purchase. It was listed on Armslist about 90 miles away.

The 1912-18 I was able to find from another local collector who also sold me an M/24 Finn Mosin with a Bohler-Stahl stepped barrel. That is also where the Kort bayonet came from. The long bayonet I also saw listed on Armslist.

Karabins show up on Gunbroker from time to time. I do believe the 1894 Rifle is the only one I have ever seen. Is is sort-of-bubba'd with the reblueing and parkerizing, but remained uncut. It also has a much better bore than either of the Karabins.  All of them probably shoot better than I can, anyway, regardless of bore condition.

Keep your eyes open! I hope you get surprised like I did.
