Never heard of this call. Is it a mouth call or a tube call? Assuming it was/is a tube call, from that era I would suspect the reed material might be proph...but that is just speculation. If you are looking for a recommendation as to what to replace the reed material with, I would suggest something (latex) in the .003 -.004 range, but there are other choices, as well. As for the width question, it seems to me that most tube calls...even from that era...have a diameter of about 1 1/8 to 1 1/4 inches or so.
Again, though, just kind of guessing about it to try to give you an answer to your questions...
