Hi, Yes,it is solid silver of 13 Loth fineness (.812,5) and the maker is Neresheimer & Sohne,Hanau,Germany. See here: https://www.925-1000.com/Fgerman_hanau_marks_01.html The image of the whole item is always helpful;Hanau silversmiths made reproduction silver reminiscent of previous periods (e.g.Renaissance). Regards
Do not worry;it IS silver. As I said the fineness is expressed in old German unit Loth (number 13) equaling .812,5. For example,sterling is .925 meaning 13 Loth or .812,5 has a bit less silver in the alloy, but still SOLID silver. Regards
