Hi Forum
I have just got this RAD Stikpin, ca someone help me with markers mark, I read perhaps:

Markers mark:
RZM
DR.S.& CO or DR.F. & CO

The maker is Dr. Franke & Co. of Lüdenscheid.

The triangle with the letters "RLAD" (the "L" being a mirror image) below the abbreviation is the RAD's Zulassungszeichen [authorization mark].

The circular marking on top is not the RZM mark (which should not be present on an RAD pin anyway), but I don't see it clearly and can't positively ID it. (Most likely, it's the maker's logo.)

It looks like the Dr. Franke maker mark in circle...

Hi Gwar
Thank you for your help and ID, the stickpin is covering the circle and I cannot move it, but I think you are correct about makers mark in the circle
