Got these two from Apex the other day. They were manufactured by Hosiden Besson, which was established in 1957, trading as A P Besson and Partner Limited manufacturing earpieces for the National Health Service. They work well as mic so now its time to build them some sort of housing.
They were in fact manufactured for the G.P.O ( General Post Office ) for use as the earpiece in telephone handsets. Like you said though they do make good microphones even though that was not their intended use.
