Nice pics guys. The last shot, of the cockpit, is more or less as it should be, although this Lanc has dual controls fitted. These were a 'bolt on' accessory, removable, and operational Lancs only had the single control yoke, and no rudder pedals to bang your head on when entering the bomb aimer's compartment (it bl**dy hurts when you do it, believe me!!).
The early Lancs were painted in the Cockpit Grey/Green on the entire inside of the fuselage, but the forward section was soon painted in a semi-matt black, and this was later done at the factories. This was to reduce glare, and the possibility of the lighter painted areas being visible from outside. From the main spar forward was black, (thast's from the radio op's station, where the transit joint is) the remainder of the interior being in the green grey colour. The pilot's seat was black on all models, with the arm rest and back padding in dark brown leather. The pilot's head armour was normally the cockpit green colour, with a yellowish green circular 'gas' panel, although these were sometimes painted black, especially on the rear surface. The armour was sometimes removed late in the war, but AFAIK, 'George' retained this armoured panel, which was from the floor to above the pilot's head.
The two support stanchions between the nav and radio op stations, and the hand rails down to the nose compartment were often overpainted black, and were eventually re- painted yellow, particularly the hand rails, as a guide in the darkness. The fuselage decking behind the cockpit, under the canopy, was in the external camouflage colour. The 'open' part of the main spar, the notorious 'knacker cracker' which had to be clambered over to reach the forward section, was directly adjacent to the radio ops position, whio's seat was actually on the spar flange, and this had a curved alloy plate covering it, again painted black, but often worn with dull metal showing through. But it's unliklely this will be visible in 1/72nd scale.
If you decide to open the rear entrance hatch, the the door opened inwards and forward, and there was a step, or plate on the lower lip of the door frame, over the ammunition tracks, which was originally painted the cockpit green colour, but often coated with a dark grey anti-slip material. The inner surface of the door was also cockpit green, and the colour was just visible on the door edges. The boarding ladder was black.
