If I were a true sleuth, I would take into consideration that they are making great copies of facebeads and other complex cane varieties with ease, I'm sure many buyers have been duped by excellent reproductions coming out of Iran and Crimea to name just two locations known for great fakes, your arguments make sense if there were NOT an already thriving industry making these types. I will grant you that there is no norm or standard type and the beadmakers from similar eras made "close but no cigar" bead types in varying locations, this does not change my opinion and I still say the bead appear to be modern repros
