Diaphone Profundo English/Italian?

This stop is unique in the organ world, being the only 64' Diaphone in existence, and one of only two true 64' stops. The other is the Contra Trombone in the Town Hall, Sydney, Australia. Irwin mentions this stop, saying only that it �speaks very promptly�.

Example

Diaphone Profundo 64', Pedal; Convention Hall, Atlantic City, New Jersey, USA; Midmer-Losh 1929-32.
