Thank you for your input. Those vases are definitely a similar shape. Did you look at the link in my last post?
However the consensus seems to be that Kralik didn't use applied snakes, only Loetz and Rindskopf did. Kralik did use applied trailing (?) but not snakes. Are you familiar with this? This has a definite head with 2 eyes. I know nothing about this sort of glass, so am just repeating what others are telling me :-)
cheers
