The SWELL, 3^rd manual, is on wind pressures of five to twenty-two and a half inches. All are under expression, in two boxes (low pressure and high pressure). The low pressure chamber houses the Original String division designed by George Ashdown Audsley—the first independent String organ ever found in a pipe organ. This String division is restored in 2018.
