Hello Silverfan and Baher
many thanks for both of your comments and opinions.
My feeling is that you are both not correct.
I feel it is The Reiner mark.
As for your comment Baher ,"they never made silverware like that" I have posted images of a small box with their mark ,to prove they made boxes like this.
I have contacted the company as you suggested ,waiting for a reply.
I am not sure why you do not feel it is not their mark ,it is clear to me that it is ,the bottom section of the mark.
There are quite a few marked Reiner small boxes online including the one I posted here a few years ago.
regards Guido
