We are restoring the 1867 Hill & Son organ at Cockerham near Lancaster. As usual, the leather inserts in the metal roller arms and squares have perished, and have to be replaced. They are made of leather, soaked in polish, inserted in the hole in the arm, and moulded in a press to give a domed shape on either side of the arm. The result is excellent but requires special equipment and is undoubtedly time-consuming. Here Chris is soaking the leather in the polish.
