There were only 2 criteria for the donations: the items should be made from wood and must have a story behind them. The items used vary from a coat hanger; a Victorian police truncheon; hockey sticks; large crates used to transport gold as British securities to Canada during World War II; a piece of Jimi Hendrix's guitar and a hairbrush used by a make-up artist at Pinewood Studios in the 1960s. And if I had known, my son's violin would be in it. Straight after his first lesson!
