TINKER, in picture #2 it plainly shows the chambers have been sleeved, but I dont think the barrels were sleeved as well.

In the third picture of the proof marks, it plainly shows the chambering to be a 7X65R, not a 7.65.

This rifle looks a little rough to me, and might be a pig in a poke! However if it shoots properly, and the regulation is spot on, then it would make a very good hunting double rifle!
