Would there happen to be another >>Crown over V<< on the frame somewhere? I am not sure if there was an inspector that used the mark of the >>Crown over V<< but if the Crown is different from the >>Crown over K<< and >>Crown over q<< then the touchmark might just be that of Germanic origin & it would mean that it was in a shop, onhand in early 1893.

Cheers,
