Anyone able to help me out wth this three piece multi-part. It has no markings. Stands 7 1/2" high and 8 1/2" across the umbrella. I thin it is a Pittsburg product but that would just be a lucky guess being I'm a glass collector. Would appreciate any help you can offer IDing U number and what is the average price these sell for. Would like to know if I made a good deal or not at the flea market today.
