As promised, I have now received a picture of the Imhof and Mukle (or should it be Muckle, there seems to be two spellings?) barrel organ at Speke Hall, near Liverpool.
So far, the only reference I can find is on a website:
http://www.goetzegwynn.co.uk/opuslist.shtml with the reference "1865 Imhof and Mukle clockwork barrel organ at Speke Hall for the National Trust"
Sadly, the National Trust don't play the instrument and only have a recording which they play to the hall visitors.
