Hi;
Amen on the wires ! The Collngs Foundation Bird ( I saw it weekend before last ) Was a narrow space crowded with wires and flight cables . No Handholds , remember !
The wires were bundled tightly . They ran from here to there and everywhere ! The cables were run along one side with little tensioner wheels in pairs as well . These flight control cables were exposed and very easy to grab by accident . Anyway the bomb racks were wider at the top then they narrowed to a platform that ran from the forward end of the bomb bay to the aft , just inside the bay doors .
All this and air canisters small instruments and the midship gun bays . plus the Bullet boxes for steady feed . On the flight control vables . A pair ran down the port ( left ) side of the aircraft . The rudder control cables ran directly above your head suspended by those little tensioner rollers and small brackets from every sixth frame .
The gun bays did Not have glass . I know some ( Most of the birds , did ) I hope this helps . T.B.
