I am in New Zealand.
On a local folk website,there is a Rock Chidley advertised in good condition for NZ900 dollars,wich i guess is around 600US.
I have looked around on the net a little bit and it seems that this brand was produced in the 1850's untill about 1865.
I guess it is more antique than musical but will follow up with the seller.
I note that Rock worked for Wheatstone and sometimes signed his work while there as well.
What distinctive features will this instrument have to identify it.
Did Rock Chidley produce English,Duet,and Anglo?

Grant Wright.
