Another picture showing the same area of a Lancaster. It shows more of the left side hydraulics. While there are some variations, it seems to me to be a good match.
Is the dark "pole" that runs down to the right from the center boy actually part of the ammunition feed ramps that would have gone to the rear turret? Those feed ramps are evident in the picture linked below both on the right and left sides of the ship.
