It appears it is the Nimrod Action w/ spring removers made in Suhl by Thieme & Schlegelmilch @ the Römerwerke factory / facility.
R.J. LePage was just the firearms merchant who wanted that specific platform.

I would agree completely, definitely a Thieme & Schlegelmilch Nimrod action.
I agree also, on the maker of the action. But the rifle barrels were installed long after the action was made as it was originally a sixteen gauge per the proofs. LePage, put his name on it along with the rifle calibers, when it was resleeved. Whether he was a merchant, ordering the work, or he did it himself, I could not say, but whoever did it, did a damn nice job.
