Welz Iridescent Glass Known Shapes and Possibles

The known shapes are the rosebowl centre front and the three taller vases at the back.
The possibles are the shorter vase at the back, the tiny vase to the right and the round vase to the left.
All seven have four dimples, some have long indentations and two have twisted long indentations.
Where they have metal collars or a frog, the cut out pattern on the side is the same. Furthermore it's not a pattern found on any of my Kralik rosebowls. and I have several! I wouldn't normally use metal additions as identifiers but the shiny metal tops came as a job lot purchase, all in pristine condition, so probably together in a cabinet since new,
