This is an amazing documentary article featuring interviews with George Cushing & Victor Chiappa. We also see Victor's daughter, Albert Chiappa & Mrs. Cocchi. We see the Marenghi with the xylophone working, although you can't hear it. The Marenghi plays well. We also see parts of the Chiappa works.
Dick Joice gave me an attendance plaque for taking my classic car to the 'Museum of Entertainment' rally in 1989!
Priceless!
