Another KNUCKLE Vase/Bowl- Help Needed- Franz Welz-Kralik or Someone Else

I stopped at a country Antique Dealer today and found lots of goodies they had been hoarding away for years. They knew it was Bohemian and they had labelled their items simply "Bohemian". I especially liked this Knuckle Vase/Bowl that had a very Special Finish/decor and that was quite reasonably priced, so it had to come home. I suspect that it is one of the above Czech. companies that made it but would anyone know definitely who made it and what the decoration is called. It measures 8" by 6" by 4" and has a lot of wear under-base with a very unique polished pontil base. The insides is a rich iridescent orange, the Red & Brown spatter is encased in a clear iridescent outer layer. Any help truly appreciated, RER(BOB) PS: I will list the other two Vases I picked up tonight.
