Hi,

I have never heard of such a makers mark. There is only the mark "KO" which stands for
"Königliche Münzprägeanstalt Abteilung Orden, Stuttgart".

Thanks for your reply.
I just found another thread where the maker's mark CD was mentioned.
This might be it, instead of CO.
I don't have the cross here, a friend of mine recently bought it in France.
Since he doesn't have a computer, I'm trying to find the maker for him.

thanks,
Ben

Hi,

sure, it might be "CD" also. This maker is unknown, but the moost EKs with "CD" come with a silver stamp "800". Has your EK got this stamp?

Yes, it does,
It's probably "CD800"then.
Thanks,
