I happened accross a Type M carbine w/a Kurz action last year at a local show.
6.5K caliber. No alterations to the carbine, all match, I'd say 95% orig finish.
Wasn't looking for one, just fell in love with it and thought the take it home price was right @ $2500.

I'll see if I can get some decent pics up.
I think the ser# puts it pre WW1,, my estimation of course.
I'll dig it out.
