Your Nimrod frame would have originated @ the Romerwerke / Rmerwerk/ Rhmerwerk . Jacob Rmer / Rhmer either didn't know his last name or how to spell it. He seems to jump from one spelling to another @ the drop of a hat. I would think Sauer could have forged their own frames, but then again there could have been a blank frame forge such as the Schilling forge. E. Schmidt & Habermann did their own frame filing and too might have had the capability. It may be that the Anson & Deeley Body Action and variants had to maintain a certain amount of steel for the integrity of the action, so they pretty much were the same shape.
Daly / Lindner more than likely sourced his frames from Sauer.
Have a gander @ all the mechanics @ the Rhmerwerk facility:
