Brown Glass Cups with Wooden Tree

I have searched all the glasses and pouring cups and the wooden tree, but none have any distinguishing markings or lables on them. I would really like to know who made it, so that I can tell people when they ask me about it. It really is a beautiful set, even with the few broken pieces.

The first picture is of one of the pouring cups. There are 2 of them. The on in the picture has a small chip at the end of the spout. The other is missing the spout all together.

The second picture is of one of the cups. There are 4 of them. One of them has a few cracks around the handle, but none of the pieces are broken off. It also has a blemish on the inner glass work, almost like a divit. The other 3 seem to be in good condition.

The last picture is the "Cup tree". The base is made of some sort of wood. The only decoration on it is the way the wood was carved. There is no decorative markings. It looks to be made from 2 pieces of wood. The bottom is hollowed out a little. The top is some sort of metal. It might be a little rusted, but the onder color looks to be gold.
