Unknown headstamp on 6,35 browning

This 6,35 browning landed on my desk, today. Unclear headstamp, this is the best I can make of. It came with a FN model 1906 made in the fifties. What do I have?

Hi Dirk, headstamp is R. M.S ☆. Made by Rheinische Metallwaaren- und Maschinenfabrik, Sömmerda.

Fede

That’s pretty older than the fifties. Thank you, Fede!

Fede is the world’s ammunition encyclopedia, … I’d like to see his library … .
