How can i find the manufacturer of my wine glass?  I have a few
different crystal glasses I picked up at thrift stores and would like
to find out who maufactured the glasses.  They all have different
marks on the bottom.

HI,
Probably the easiest thing to do is to take them to a larger store
that has a department for tableware and talk to a salesperson and ask.
 You can say that are considering completing a set of a couple of them
to make him or her interested and take notes about prices.
If the "marks" are little stickers on the foot of the glasses, you
could post the names in a clarification, and probably some of us can
identify them.
