At one time I had a Remington Model 30 such as yours. It was all original. Looking at the pictures you posted I am led to assume your rifle was re-stocked at some time. By the quality of the stock I would believe it would have been done by one of the premier gunsmiths of America. During this time further work installing the Stith scope mounts, scope and the Pacific peep sight was done.

I do not know if Parker did custom work. I know they were a top tier maker of shotguns. Griffith and Howe make some high quality sporting rifles. They could have done the work.

Your rifle is exceptional.
