Having a clear out, I have just listed on Ebay a 1930 National Brass Band Festival (held at The Crystal Palace) solo cornet/conductor copy of the test pieces that was produced especially to be sold on the day. Also, four similar ones from the 1920's and 1930's for Belle Vue, Manchester (obviously just one piece used at Belle Vue). Prbably unique and highly collectable. I did intend to have them framed, but never got round to it. And no, I wasn't there!! PM me for more details if you want. Julian.
