between the wars

I’m currently building Ardpol’s Curtis B-2 and can’t find any refences as to the correct colors for interior fuselage and nacels where the rearfacing gunners are. I wish the instuctions were a little clearer, no indication where most of the p/e parts go. Any suggestions would be helpful Thanks. outdoorsman

I don’t have any references for that aircraft, but most of that era were unpainted natural metal.
