Alright, is it easy to trim, what do you use for this ?

But I may have found an original diaphragm for this.
Thank you again for the help. I'll let you know how it goes.

Alright, I received an original diaphragm , and some gasket for this (thanks to Ken Priestley http://www.fonograf.com ). I just need some wax and I'll get to work.
