Many readers will be aware of Frances Broadway's postal auction
of piano rolls, 'Post Bid Enterprise', in the U.K.

This month's auction, closing on 25th July, rather unusually
includes quite a few Tri-phonola and Welte Green rolls. All are
being sold individually. Details may be had from Frances at
