RN bulkhead over gearbox

[Scarlet O'Hara]

Hi, I am trying to sort out my RN box but need some information on the shape of the bulkhead above the gearbox. I'm trying to determine if the recess behind the engine is uniform all the way down or is it tapered to become flush with the bulkhead at gearbox height. Not sure if that makes any sense but if anybody could post a photo of that area taken from the inside it would be a great help. Many thanks in advance.
