[Boatanchors] WWII headphone pads

[Richard Knoppow]

    A caution: the original rubber and leather pads can shrink or 
at least the rubber gets stiff and when stretched over the 
headphone will crack. There was a later version made of plastic 
and rubber. They probably also become degraded with time but are 
newer.
     The kind that came off flying helmets had leather covering 
over the headphone. It may be necessary to cut this out to get 
them on. The audiology phones, which are very similar, have 
rubber or plastic pads that sit on the ear. I prefer the aircraft 
type with the over the ear pads.
     I have only ever seen one of the Permoflux sets, either not 
many were sold or people keep them. These were widely used in 
broadcasting for monitoring.
