Yep, in general, the cockpit, radio room and nose compartment was the Dark Dull Green. quite close to Bronze Green. The bomb bay could be Interior Green, or one of the shades of Chromate, more towards the green than yellow tinges.
Waist area from the hatch into the bomb bay and aft, varied between a Chromate finish, and Interior Green, to clear-coated bare metal, although the latter seems to be more on the late 'J' models.
The earlier model D and on to the early 'H' and some early 'J' models tended to have a painted finish in the waist/rear fuselage. It's no wonder, with so many variations, that the 'Lib' was also known a 'The Consolidated Mess' !
Gary (Geedee) has posted a lot of interior pics of the Collings Foundation aircraft, which, in general, is a good guide to interior colours, as it has been accurately preserved.
