An almost identical cowling arrangement for the geared Jupiter as that on 9385 was tried on the Bristol Boarhound. J9385 might also have trialed this cowling before being reverted back to the contract standard and dispatched to India. The fact that the top photo is of the standard test/ trials format/view I think reinforces this.
The fairing plates at the rear consist of 9 separate plates from what I can see and easily removed. Of interest J9382 was retained by the makers and also used for several trials. I’m sure that in the interwar air force there was the equivalent of ‘Red Line Entries’ for an aircraft to be flown without damaged panels or items such as the exhaust manifolds needing repair but in short supply, so the earlier direct stubs could be temporarily fitted in lieu.
