Is there anybody in the U.S. or Canada who (as a specialty or a
sideline in their estate-liquidation business) at least occasionally
liquidates MUSIC ESTATES?  I would like to contact one, or several,
however many can be found.
*******************************************
I am not looking for people who specialize in liquidating musical
INSTRUMENTS estates, but people who have liquidated the estates of
people who were involved in the *recording industry* in some way. 
This would include such as former label owners, promotion-people,
managers of musical talent acts, employees of record companies, and
the like.  I am looking for "old paper."

The following searches have been entirely unsuccessful on Google:  ALL
PERMUTATIONS OF "music estate" and "music estates," PAIRED WITH one
each of all the following words:  liquidation, liquidations,
liquidate, liquidating, executor, executors.  Also, "music estate
sale" and "music estate sales" were unsuccessful.

I am trying to find "old music paper" from the Forties and Fifties; I
realize all too well that any such people who may have been packrats
are either old-age downsizing, or dying; what I seek is almost always
simply thrown away.

PLEASE NOTE:  This is not entirely "time-sensitive," I'd prefer to
wait if it means the difference between finding such people, and not
doing so.
