This seems to be one of Bach's works from the Weimar period.
This is the 2 movement version; there also is one with an adagio as the middle part; probably added because the introductory Praeludium is not very big in size though monumental as a composition.
Praeludium is played on a HW 16' Plenum with 8, 4, 2 coupled to the RP added.
Pedal 16 plenum + Bombarde
The fuge on 8' RW + HW Plenum coupled.
Pedal + Trompet 8'
