(rshsdepot) Telegraph sounder recordings?

["Ulster & Delaware RR HS - President" <stevdel_@_prodigy.net>]

    Does anyone know of a source for recordings of telegraph sounders?
Preferably giving train orders, of course, but anything will do.  Saw an ad
looking for one in the current RLHS bulletin, and realized that from
everything you read about an old-time depot, you've just got to have this
sound going almost continuously in the background if you're going to make
the place authentic.
    Thanks
