Vase

[Mblossom]

I have an old bud vase.  The friend who gave it to me said it was around 100 yrs old.

It's aproximately 12" tall; about 1 1/2"across the top; it has gold around the rim and about 1/2" down and also on the base.  It has a mark that is a U with filled in circles on the two ends of the U and has a circle around the U.
I would like to know if anyone is familiar with that particular mark and if they can tell me anything about the vase and maker.
