Here is a 1950Model Mannlicher Schoenaur.
9 IIRC drilled and tapped extra holes in the action for 2 different scope mt bases.
Right thru the factory lettering in many instances and those on the left side of the action ment thru into the inside of the bolt raceway as well.
The metal had all been buffed and reblued at some point too.
Damage from the D&T jobs plus rust and old epoxy used to fill the space meant for the factory dummy side plate when the actual scope mt on the side was not fitted (which it was not)
Broken off screw in left side of recv'r.
Holes cleaned up and filled with plugs,,no welding done.
Factory lettering recut and that which was removed during the D&T processes is put back carefully by hand engraving. Surfaces polished back to clean sharp edges and contours. Inside of bolt raceway polished to to leave clean smooth surface and any sign of the old mount screw holes that poked thru.
The rest of the metal polished by hand to reclaim flat surfaces, sharp edges and proper contours from the prior buffer job.
Factory lettering on bbl, floor plate, even proof marks etc were recut.
Then the parts were Slow Rust Blued.
The stock was in fine shape and simply cleaned up. The epoxy filler that was slapped into place to fill in where the factory dummy side plate rests was removed of course. The void was filled with a carefully cut piece of wood and made to match the stock profile allong the action in that area.
I made it only approx 1/4" in depth into the cavity itself so that in the future someone could (with care) cut that section away for a side mount to fit nicely and not have to inlet the full depth.
The owner expressed no intent on using a scope on the rifle, but he appreciated the work being done that way.
The Rust Blue was a simple set up as you can see.
The most complicated machinery involved in the job was a drill press. Other than that it's all common hand tools.
Learn what you need to do, Practice and keep at it. Don't let anyone tell you it can't be done.
Don't watch the clock,,,that's for jobs you don't like showing up for.
