It's my understanding that when Walt Bellm passed away, his son (or
son-in-law?) took it on to sell off the Museum.  I believe Bill Endlein
(Eastern Musical Antiques) moved to Florida from NJ to sell off the
collection (Bill has a heck of collection himself).

Bill lives in Fort Myers now, and may know more.  He is not on the net,
but is in the book.  (I worked with Bill back in the 70's at Yesteryear
Museum in NJ, but don't keep in touch).
