Hi brubaker50, and a belated welcome to the GMB.
I was hoping that somebody knowledgeable on Loetz items might have replied. But there can often be a delay in responses as not all people browse the Board regularly.
I have removed your additional post from the "Bohemia, etc." forum. When we get some positive replies, one way or the other, a moderator will move the whole thread to the relevant forum.
Personally I have little knowledge of what may be generic Bohemian items. However, it looks to me that your vase has an allover satin finish and I do not particularly associate that with Loetz items, which are more likely to have an iridescent finish.
Have you tried these sites?
