inventor Posted July 14, 2004 Share Posted July 14, 2004 Several Patents using this type of keyboard were taken out by Dr Pitt-Taylor. these were G.B. Patents: 1916 No 102552, 1922 No. 208274, & 1923 No 220824. I don't have these patents to hand but I am fairly certain that one of these almost exactly corresponds to the one you have described. He also took out a number of other Patents during this period but more on Maccann style. A Mr Mitchel also took out a number of patents at around this period from 1912-1930 which were more on the Piano Style. A full listing of these can be found in the "background to the invention" section of the Hayden Patent - GB 2131592. Regarding Wheatstones listing it as a "Piano" concertina system; I note that the first Hayden System concertina made by H Crabb & Son's is listed in their ledgers as a Jeffries Duet type system; but is only similar in the way the buttons fall on the concertina, not even remotely similar in the notes that each button plays !

Regarding Wheatstones listing it as a "Piano" concertina system; I note that the first Hayden System concertina made by H Crabb & Son's is listed in their ledgers as a Jeffries Duet type system; but is only similar in the way the buttons fall on the concertina, not even remotely similar in the notes that each button plays ! One I've been experimenting with is the Pitt-Taylor 1924 layout. I'd say it's about as much like a Jeffries duet as it is like Maccann, or about as close to either as the Hayden is to the Jeffries. And the Wheatstone ledger lists the P-T 1924 with a Maccann model number and just the word "Special". Link to comment Share on other sites More sharing options...
aeolina Posted August 25, 2004 Author Share Posted August 25, 2004 At long last I have posted a photo of the actual keyboard of my duet with notes attached. I hope this posts properly. Stuart Link to comment Share on other sites More sharing options...
