Vienna maker KK

[EmmaW]

Can anyone help with the mystery maker KK? I've got that the box is Vienna, .950 standard, 1872-1922 but the maker's mark eludes me.







I've found another example of their work, but they too only had KK in their cataloguing.

Whoever KK is they seem to make quality stuff and I'd love to be able to put a name to the item.

Thanks everyone.
