Just recently on another forum I presented some research of mine regarding these marks and why I think they are, indeed, those of Georg Roth of Hanau. Hanau makers sometimes - but by no means always - used their trademarks alongside pseudo-marks. Wolfgang Scheffler, in
Goldschmiede Hessens, made the first systematic study of Hanau pseudo-marks. He started with items bearing a maker's known trademark or items with pseudo-marks which by other means could be positively attributed to a maker. Then, he noted any spurious marks appearing with these marks. By this comparative method, he was able to identify even more pseudo-marks. For instance:
Mark 1 shows Roth’s presumed “official” mark (Scheffler #550) and two pseudo French marks, the crowned A and P (Scheffler #s 549 and 551, respectively). From the crowned A and P, Scheffler was able to identify two more marks as Roth’s as seen in Mark 2: the crowned fleur-de-lys (Scheffer #552) and the crowned KW (Scheffler #555).
All of these marks are shown in Scheffler as noted and attributed to Roth. Extending his findings, I note the following:
Here we have the crowned KW (Scheffler #555) from Mark 2 appearing three times with the crowned G in question - twice with the cross, as well. I believe the third, faint mark on your spoon (and probably that in the moderator's small photo as well) is Roth's crowned KW, which I have now seen so many times with the crowned G and cross that I have no doubt that they are Roth's as well. Certainly the "medallion and garland" style of your (condiment?) spoon is entirely consistent with Roth's output.
I note, too, that this “crowned G” is incorrectly identified on the “Germany before 1886” page in this forum as the Gorlitz city mark (which was a crowned G, but I'm pretty sure the one illustrated there is the pseudo-mark discussed here).
