Napkin rings mark 800 k&k

[Phate008]

Sorry if this is in the wrong place. I couldn't find a mark like it and thought the German marks were the closest fit, but honestly it may be some other country. It is marked 800, a crown looking object, and either K&K, KSK, or K (unknown character) K.

Hello, most likely Kirchgaessner and Kraft from Pforzheim, a maker of jewellery and small silverware, also a retailer. Regards, Bahner
