This silver spoon is marked with a minervahead F for Friesland. The makersmark looks like a 77 but I cannot find a match for this one. With Brunings or Bruinings the 77 is above the letters. In this case below. Any idea?
I'm afraid the mark is illegible, especially when you rotate it, no clear letters or numbers emerge. Incidentally, the regional assay office letter could indeed be an F for Leeuwarden, but it could also be the letter E for assay office Groningen. Unfortunately, I cannot link a silversmith to the master's mark. The yearletter r is for 1876.
