I have this model of a violin, hollow, but with cast silver top and bottom. Purportedly, it has a maker's mark 'CU' and partial Amsterdam city mark, but I'm not sure, so I'm checking with the forum. Initially, I thought they were pseudo marks and part of the casting, but the back and front of the violin are each made of two joined panels of the same scene (four panels in all, though one with an applied bridge and one with an applied neck), and only one has marks. So perhaps they are real, after all. I would be interested in the forum's opinion. Whether or not they are real, who's mark this is and what is the approximate date of the piece? If only a pseudo mark, obviously this wouldn't be the real maker, in which case is it a Dutch or Hanau piece?
