And the penny whistle evolved, in England, from the English flageolette

The key to this one is in the name, WAV, which Generation (still?) use, somewhat confusingly, for their whistles. In any case the penny whistle most certainly did not evolve from the Flageolette, which is an 18th (?) century contrivance albeit of a similar lineage to the internationally ubiquitous whistle flute of which the British penny / tin whistle is but one manifestation. I have an early 20th century German example (in E!) of a tin whistle made in the traditional manner still used by Clarkes. Once again, WAV, you're twisting the facts to fit your tiresome nationalistic theory, thus casting your academic credentials into further shadow. There are English Jew's Harps too, very distinct in their rather robust construction, albeit dating from the 19th century, and quite possibly known as Trumps; just as in Italy they're known as Scacciapensieri, in Germany Maultrommel etc. etc. In any case, the penny whistle, like the Jew's Harp, is no respector of national boundaries.   

And as for the English Tittyfuck, Catspaw, in England it's commonly known as Spanish Sex (hence WAV's where does the rain in Spain tend to fall? presumably), or, as famously immortalised by Glen Miller, String of Pearls. In Tyneside I've heard it referred to as a Longbenton Tit-wank.
