I'm not sure why the scope mounts on the side since Model 50s came D&Ted for standard Mauser mounts from the factory. 60 years ago when these guns were new scopes weren't as trusted as they are now and perhaps someone wanted to be able to switch back to the irons quickly.
If you restock it you must be sure that the stock dimensions are exactly the same as original. The Model 50 has an unusual two piece trigger where the sear is in the action but the trigger is in the trigger guard. The trigger may not work properly if the distance between the two is not exactly correct. Or you could just replace it with a Timney.
At any rate they are very well made guns and extremely accurate. The actions were made by FN in Belgium and the chrome lined barrels were made by High Standard.
