The above photograph shows two silver flute body tubes. The upper one is an old Rudall Carte body tube which used to be the Flute Maker's own flute - made himself when he worked for Rudall Carte.. He now uses one of his own flutes, and the lower tube is a tube with no holes yet drilled in it. It does have the maker's name and flute number encgraved on the tube.
Photographed in the workshop of UK Flutemaker Ewen McDougall of Ravensworth.
