Paki No. 4 Mk 1

Saw a Pakistani No 4 Mk 1 today, dated 1953. All matching, stock, bolt, mag, Good stock, better than some old ratty beaters we see now and again.
Problem is the bore. Don't get me wrong, here. I;m not a pristine bore purest. If I see a needed piece, I'll get it if the bore is even passable. (who am I kidding, I've not even looked at some I've bought!)
This bore is gross. Black hole. No lands or grooves. Rust top to bottom side to side. Worst bore I think I've ever seen, and that is a bunch.
Guy said he knock off another 20, but I think I'm going to pass.
Anybody need one? They didn't make many of these.
PS had the Ishy screw.
