Sorry, I do seem to be taking up a lot of topic space ... but I have nearly finished cataloguing my bookmarks/fruit knives and I think this is my last query! This sliding blade silver fruit knife made in Birmingham has a makers mark which I think is THV and a fairly curly e date mark which is probably 1904 but to my inexperienced eyes could be 1879. The handle has a clearer date mark and lion, but no makers mark.
