Next up, the outrigger engines.

Historical note: These airships had the engines inside the hull (as opposed to being carried in pods outside the hull as on the "Hindenburg" and most other airships). The propellors were on mounts which could be rotated 180 degrees (a "tilt-rotor", if you will!), enabling more precise takeoffs, landings, hovering, and dynamic lift (ie if the ship was too heavy).

This is going to take some doing. This is the only picture I have of the engines in close-up. I am going to try and get in as much of the detail as I can see! Here is a picture...
