There's a good chance it is what you say, enlargement and inspection of photo reveals it is not a re-etch but a Rohm inscription on an SA dagger by F Dick. There is a noticeable difference between the burnish in the trademark and the inscription so the possibility exists.
It would have helped to have the edge of the crossguard in the photo and also to have the blade perpendicular to the camera rather than at an angle. When you get the right condition of lighting angle etc. You can make a comparison like this one, but still this one could be a lot better.
