I have one labelled THE CHANDOS, likely English manufacture c.1900-20, but could also be American.
An American parer/peeler with the same shape of the fruit holder was made by the Goodell Co of Antrim, New Hampshire, as the ‘Success Orange Peeler’, using a Fred G Mower patent (number 1,008,555) dated November 14, 1911.
The Goodell parer’s instructions advised that the knife was set for large fruit but could be adjusted for small fruit.
The Goodell parer does not have the same gear number and arrangement as the Chandos or probably as Mr Horlock’s machine. The ATG image does not show all the detail but perhaps Mr Horlock has other views of his parer and I might then be able to comment further.
I attach an image of the Chandos which indicates the similarity.
ATG notes: thanks also to Tony Wheal of Laxfield, Suffolk, who pointed out that the object “looks exactly the same design as my spiral fruit peeler”.
