Pepys played it
Talk about useless factoids: the flageolet does look just as I remembered it did. The link was found through the Pepys annotation pages. The Tonette is still made; mine was marbled cream with maroon trim. If I ever unpack that old footlocker from the Great War, maybe I'll find it and my recorder. They all have fipple mouthpieces, as does my old slide-whistle shaped like a bird with a beak that opens and closes to produce a gargling effect.
