Req. for info. on dia. diaphragm etc of Vicsonia reproducer

[A Ford 1]

Hi all,
I wonder if some one could answer the questions:
1) What was the material used for the diaphragm?
2) What is the diameter of the diaphragm?
3) Were there one or more adapters to connect the Vicsonia to the Victor and Columbia tone arms or were there two different Vicsonias made?
Thank you all Kindly for any input,
Allen
