If I am correct Peter and your weight, my weight and ebay item num 1906 3959 5477 are all the same maker, which the canes are to me, it will be interesting to see the final bid on this one.
Notice this one is not identified either, not even as Murano. I would have thought someone would have the knowledge to ID these a bit more accurately even to a decade and country. "Vintage" to me doesnt mean anything much unless accompanied by "deco", 50s, 80s or something similar.
