Horace, There is not much chance of finical help, however the UK piano trade is v.help full I may be able to get old of the Broadwood papers, Now that will be interesting as Broadwood kept a lot of records, also I had a call from Liverpool yesterday I _May_ be getting the Rushworths sales ledgers, a lot of pianos made for Rushworths were sold as stencils for other shops to put there name on, some of them were in the US. Most of the UK patens are now being put on micro film. The London office is not v.helpfull in doing traces, the Leeds office on the other hand are relay good, but it helps as the man is a keen piano player so he enjoys it. The sad one was Kembles, they keep records of who bout there pianos, unfortunately all these records was thrown away by mistake. The good news Iback are in the process of putting there sales ledger on the web.
