Rear right corner of the passenger compartment, with corner of the ceiling and right C- and D-posts of the body. The ceiling at the right shows that the upholstery was glued against the metal. The ceiling to the left has its upholstery glued on a wooden foundation plate which is then attached to the ceiling by screws and clips. The reinforcment beam in the ceiling (to the left of the centre of the upper half of the picture, starting from the C-post) is where most landaulette conversions stop. Taking that beam away requires compensating reinforcements via the sides and the floor of the body. But leaving it in place means that passengers cannot stand upright through the open roof, since that beam is just above the front edge of the passenger bench.
