Thanks for the welcome
I have checked out many on line resources and still can't find this exact shape.
I've seen one other that was identical and it was unsigned and unattributed.
Though, as you said flying free it does resemble Kralik Silberband. There is a
section on the loetzandglass website that highlights what appear to be very
similar pieces in wide variations. I'm working on getting the pics reduced to
an acceptable resolution, Lustrousstone, sorry for any inconvenience.
