That listing misses some detail to be found here: https://www.npor.org.uk/NPORView.html?RI=D03668 , such as: pedalboard is radiating concave; extension work on the pedal stops (only four actual ranks of pipes in addition to the mixture). Neither listing makes clear whether the reeds shared between pedal and swell are enclosed.

Neither listing makes clear whether the reeds shared between pedal and swell are enclosed.

They are bound to be if they're shared ranks under expression in the swell box. Well done for finding that. So much more info. Possibly too much extension for a purist's taste, but probably a very effective accompanying instrument.
