Hanau ?

[amena]

A friend asked me for help identifying this hallmarking.




In my opinion these are Hanau marks since I found some very similar ones in the dedicated section that are attributed to different silversmiths.
Other marks, on the other hand, are different from those listed.
Any information will be appreciated
Best regards

Hi,
Schleissner used crowned mark with the letter combination RC (in their 1910 catalog).
Of course, perfect match of Hanau marks is seldom expected. But RC of Schleissner is more distinctive than e.g. letter A with acorn above used by Storck and Sinsheimer. Therefore, I opt for Schleissner.
