Is this Swedish? Don't think it's Polish.

Hello,

I've spent hours on the internet to locate this hallmark, unsuccessfully. Do you recognize it? For some reason it resembles one of the Swedish hallmarks I came across. It's on a fish fork.
thanks

If those are all marks you have, it is not of Swedish origin even if the mid mark resembles the old town mark of Uppsala town, sorry.

Hello, have seen the center mark on pieces of Polish silverplated cutlers. Don't remember the letters to either side, might have been the same. A pic of the whole piece might tell more. Best wishes, Bahner

Ups, should have read "cutlery ", not "cutlers". B.

You can actually see the silver flaking away from the base metal. Definitely plate.
