Well,, one suggestion was something called a “pass cup” and another was a “tastevin” or simply put a wine tasting cup !! I have found nothing similar except the wine taster which is usually silver but can have 1,,2,, or 3 handles !! But since we can find nothing definitive ,, I would suggest you go to the “Corning Museum of Glass” website !! They should be able to help !! Everyone says they are friendly and do their best to help !! Just explain if you do not know the exact details and estimate size ect !! Please come back here and update this post so I will know what it is and if I get more opinions I will post them here !! There is one member I am waiting on and he can usually find these odd items if he doesn`t know !!
