Being the 2 week wonder expert on glass, let me say that I believe that f-f's Harrach/Mulhaus is correct.
In case I cannot find a thread to link to this auction:

Lot 396 pair of Continental glass ewers(to die for)
Lot 421 pair Bohemian glass decanters, late 19th Century
If there's any money left over in the site's piggy bank, you could add this
drop-dead Bronze of a horse and jockey: Lot 25. The tie-down has been broken and is wrapped around one rein(that oddball flying piece) . The patina is lovely, if a bit rubbed. The horse is being pulled-up--he is not trotting. A horse does not trot with its mouth open since the rider is pulling on the bit. Duh.
