Thank you, all.
Ray, the mount was a sub-$20 one from eBay. Threads are so coarse that the bolt rattles in the threads, even when tightened down. Took the rear sight ramp pin and drove it through the opening, tearing the threads. Seems to be tight now. Had to be very careful not to over-torque the allen screws.
Go to the Guns and Game forums and to the Mosin-Nagant site in there. Some ads, a wealth of information, and very good guys.
The scope was dumb luck. Bob was selling it for several days on another forum and I had not noticed it. It sold for about half list. I got very lucky.
Gunfucius, I did mount a pistol LER on my Spanish Guardia, but the recoil over-came the tension. The gunsmith drilled two holes and put small scope mounts on the top. I now use one of them as a peep sight and hunt over iron.
It worked well this past season.
