I did measure up my spare room but unfortunately it just won't fit!

This looks like the organ which Henry 4 built for Sheffield University and, when it was replaced with a larger instrument by Hill, Norman & Beard in about 1977 (I was at the opening recital), went as a secondary organ to Sheffield Cathedral. Peter Wood added the Great Fifteenth, which had been prepared-for. It looks as if it has been through some rough times, but would probably restore quite nicely.
