In general, a majority of threaded glass attributed to Pallme Koenig is actually Kralik production. PK threaded or veined production is in general quite a bit more organic in form. Loetz did not actually make a decor much like this, and attributions to Loetz are generally hopeful sellers

The three pics added here are to show a different in aesthetic between a PK decor, and Kralik's decor shift of that decor. The overall aesthetic difference seen in the first two images, are similar to the aesthetics if I accumulated images of Kralik and PK threading. I happened to have these handy. Pic 1 is PK. Pic 2 is Kralik.
The third image is of PK threaded production, and I think the difference in aesthetic between those, and this example is like what is seen in the first two images.
I am pretty confident that your piece is Kralik production.
Hope this helps clear it up for you.
