800, Maker RR

[orthogonal]

Today I received this stopper. It's nicely made, I'd love to determine the maker. Any idea who "RR" is?

800, RR (?), no further marks
Possibly Germany, around 1900 (?)

Thank you! Thomas

Maker could be Roßdeutscher & Reisig, Breslau (Schlesien).

Wow, that was quick! Looking up "Roßdeutscher & Reisig" I didn't find exactly this hallmark, but a few similar with a double-R. So it is very likely you hit the mark. It's not easy to get further information about this company.

Thank you a lot for your support!

Thanks Trev! I saw that one, but the shape of the letters and the outline varied, so I was not sure. Meanwhile I noticed this old thread:

In all probability it's the same hallmark, and they all are from Rossdeutscher & Reisig.

Thank you all!

Another idea: Could it be JR Rosenmaier (jeweller, Augsburg)? It would be an interesting match, because the stopper looks like a "Zirbelnuss", which is in the crest of his city. https://de.wikipedia.org/wiki/Zirbelnuss#/media/File:Augsburg_wappen.svg
