I am hoping that someone will be able to assist me. The pictured piece of silver is Danish in origin (confirmed by the Hallmarks?) and I think it is from around 1854. The makers mark is ATD. I have been told that this is the mark of Albert Telemach Dreboldt who is my great, great Grandfather. I am wondering if anyone knows how to verify this please? I have not been able to find any record of makers marks that early, however I have found several pieces with this mark that are attributed to him.
I would be most appreciative of any assistance that anyone can give me.
