NOS Western Electric Receiver Diaphragms. Vintage Original Part

Description

Original New Old Stock Western Electric telephone receiver diaphragms.  Upgrade your telephone receiver for better sound quality and presentation with these vintage diaphragms.
I have showed photos of the diaphragms that I usually get on receivers. They are rusted, with missing paint.   Also shown is the NOS diaphragm mounted on a Western Electric 75Z receiver element.
You are bidding on ONE diaphragm.  These are very very difficult to find and are an Original Replacement.
You will receive the diaphragm only as shown in the photos.  The receiver element is NOT included.
