Re: Yugo M48?
They are very common guns, and not especially valuable or of collector interest. At best, they are worth only $200 or so. But the previous owner ruined that rifle by messing up in an attempt yo drill holes for scope mounts. The holes are out of line and incomplete; they appear to have been done with a hand held drill. The result is that the gun can't feasibly be restored to its original condition, yet I suspect it will be very difficult to either weld up the holes or to drill the holes properly. (Yes, I know a good worker with a MIG/TIG welder can fill the holes, but they will still be obvious. Also, check the cost of doing that vs the value of the rifle.)
It should be OK as a shooter, but that is about all.
