On Wednesday Bonhams auctioned the main collection of Michael
Bennett-Levy, a well-known dealer in technological items.  Here is
the catalogue along with prices achieved:

Lots included clocks, Geissler tubes and an important collection of
early TVs.  There were a few mechanical music items of interest:

Some of these items went unsold and hence do not show a price.  They
may still be available at nominal prices if you contact Laurence Fisher
at Bonhams -- contact details are in the catalogue.

Go on, I'm sure you want that harmonium!
