Dan, the poor quality of the pictures of the full gun make it impossible to tell anything about it. The close-up of the inspection stamps and arsenal eagle make it appear to be an Imperial (1918 or before) Luger made by Erfurt. The forward toggle should have the word "ERFURT" surmounted by a crown.
The stamp of a crown over the letters "RC" indicate that some part of the pistol failed to meet specifications but a "Revisions Commission" found the part to operate correctly and passed it for use. That absolved the normal arsenal inspectors from blame if the part later failed.
If you would provide more detail about the pistol's markings and stamps, we could tell you more. Otherwise, we've gone as far as we can with the limited information you've provided through your pictures.
