Hey there!!
I've just opened my recently arrived trademark and I have found this diaphragm which pretty much looks like the original 1952' part.
I have disassembled it removing the rivets, detached the membrana and cleaned up the parts.
The membrana seems to be made of tissue recovered by what was once probably rubber like material now completely useless, falling apart and cracked.
I would like to keep the old fashion look and "rebuild" the diaphragm replacing the tissue part,
what do you recommend me to use to replace the tissue membrana getting as close a possible to the original look?
Thanks for the help!
Cheers!!
Stéphane
