The latest Post Bid Enterprise auction catalogue has 700 music rolls
listed, and this time there is a surprise lot: a dual scale pushup.
These instruments rarely appear and the starting bid is £2000.

This is Catalogue 84, and the sales have been issued three times
a year, enabling me and others to acquire many musical gems over the
past 20-plus years.  Email bids are accepted; for more details contact
