Very nice details! I have never seen dark underside fuselage inspection panels (at least I assume these ARE panels!) on other drawings. On photos these are clearly visible.
All that has been published so far is based on De Havilland drawing material since none of the prototypes can be checked in a museum. We already know from Fokker S.14 that even company general overview drawings not always reflect precise details on the 'real plane'! In this case you can only carefully study existing photos for all details// Think we are writing history with these drawings.
And don't forget to remove inner pitot tubed on wingstips; TG283 only had only one at each!
