The prick engraving to the back of the terminal is 'Peter Dittmer 1886' (not shown). The stem carries the name of either the silversmith or the retailer, but is imperfectly stamped, with the leading letters indecipherable, at least to me since I'm not familiar with German makers and don't have the right books. There are no other marks on the spoon.
Can anyone identify the maker/retailer for me and where/when they were working?
Many thanks,
Silverk.
