Welz Spiraloptisch
The shapes shown on this page are those which I feel confident were produced by Welz.
There are also other shapes this decor is found on, but in light of no supportable evidence as to which house made the shape I have omitted them
from this page. That is not to say that Welz did not produce them. It only says that I can not support the claim they did, so I will not post them.
