I was hoping someone on the list could help me with a couple of detailed questions on a Hexaphone. Here we go. Besides the name plate, what is/are the significant difference(s) between the 102 and 103 models of Hexaphones? Is there any documentation out there on serial number series of the different models? Is there any good documentation/ information available on Hexaphones? I'd really appreciate any help that the list can give to me off, or on list.
Thank you very much Shawn O'Rourke
