I remember reading, although I do not remember where, that some workers migrated fairly early from Bohemian production to English. If this is accurate it would help to explain some of the striking similarities that lead to some incorrect attributions. There is, I think, (I was guilty of it myself if you see my opalescent vase post) a fairly common and widespread misconception that a lot of the footed vases with this style of applied foot are English in origin.
I realized several years ago that this was not correct, but for some reason never applied my new found information to the Kralik piece I was still researching as English.
To me the color combination in the glass (forget the foot and the applied decor) just say Bohemian quite clearly.
I think there is most likely a fair number of early attributions, that if viewed in the light of today's knowledge would end up being credited to Bohemian production and not English.
Truitt's Bohemian Glass 1880-1940 shows quite a few examples of Kralik production with applied decor distributed by Hosch that, IMHO could pretty easily be seen as English without the knowledge provided by the publication of that book.
