Jindrich, thank you for the additional information... it's fascinating. I also suppose stranger things have been seen in glass.
So how many 13139 vases have you got? I think the rest of the world has a hard time finding any because you (and px) probably have most of them...

Dirk, my amber one isn't in 100% perfect condition either... there is a small knick near the top edge, a long but slim air bubble in the fold, a 5mm fault going horizontally through the body, and a few chips to the base. But nothing which is terribly disappointing. When I saw it from a distance at the market yesterday, I couldn't contain my excitement. It was placed right beside the Brabec vase I posted in another thread. I don't have a poker face, so I just paid what the seller (a young Slovak) was asking -- 25 PLN (about 6 Euro) per piece. I came home feeling like a hero.
