I've rechecked the Loetz.com site and the Pallme-Konig Pge 2, Picture 18 seems to match mine closer in overall style. Photo 18: a 16" "hyacinth" vase from the same family, with a metal-covered base (see Brohan 192:281; Pazaurek/Spiegel 50:74 for other versions of the same vase). Although mine doesn't have a metal covered base.
As for the reference for other versions...anyone help me on that? Why is there not a dumb blonde emoticon...
