unusual Silver hallmarks

I would love to know what this hallmark is ?. It is a lovely basket type silver with blue liner .It was just sold to me as continental silver about 8 years ago

try to focus in the city hall mark. I cant see it, but it could be Austria Hungarian. But I cannot see the mark clearly so better picture at we can see.

based upon style 150 to 180 years old. But when we see mark we caan tell.

Thank you. Will do my best. I am no very good at this type of photo
