I too recall, circa 1969, seeing an organ with ranks of paper pipes in a church some miles North of Norwich, near Blickling Hall but not Aylsham. It was not in use. There was also a main organ with metal pipes in the church.
The books with very detailed instructions of making paper pipes (and others) is 'Organ Building for Amateurs' by Mark Wicks, Ward Lock and Co 1887. I think OHS did a reprint some years back.
