This is the "TRIMM FEATHERWEIGHT" earphone, made by "TRIMM INC. of LIBERTYVILLE, ILL., U.S.A." It once served duty as an 'audio reinforcement device' (read: hearing aid) that lived in the pewback hymnal racks at a church, plugged into an unobtrusive little brown box with a 'volume knob' which was hooked into the speaker/microphone system, to allow the old folks to hear the sermons better.
Its earpiece is at the end of an extendable (bakelite, probably) handle, about 10" long when collapsed and 16" when fully extended. Its cloth covered cord is still in perfect condition, with a right angle 1/4" phone plug (by SWITCHCRAFT) on its end. I don't know forzactly how old it really is, but will guess 1940's-ish.
Somewhere around here I think I also have another one or two of these (along with a few of the little brown boxes) having got them all years ago while 'on the job' replacing an elderly (and failing) church sound system.
