I have for sale the first production model penny chanter made by David Daye. It came to me by way of my friend Janice who had this to say about it:

I initially offered it to David but he told me he’s happy holding on to his own prototype.
If you are interested in this humble little piece of history then drop me a line.
Will load up some pics soon.
