Port view of the whole motor illustrating a Walter 109-509.A-1.

Points to note are these - running down the top of the thrust tube are three lines. The two silver coloured pipes are the C-Stoff coolant outflow and return lines. The dark coloured tube is the run carrying the electrical services to the combustion chamber.
(Combustion chamber temperature sensor, fire warning sensor.)

The large plate stuck on the forward face of the top of the motor, near the fuel flow and pressure equalising unit (seen here edge-on) is the holder for the exhibit caption, from when the motor was on display in the central London museum.

The metal tube lying on the pallet underneath the thrust tube is the motor support. Due to the way this motor has been displayed on small blocks, the support is not required, nor is there room to fit it.

The red item on top of the motor frame is an old museum label.

 

Port view of the main motor frame.

The large, naturally coloured steam generator is a fair representation of a wartime finish. Due to the high temperatures existing within, this unit would not have been painted in conventional metal paint, but protected from corrosion by coating with a mixture of oil and graphite. Compare this finish with the painted unit displayed in the NASM.

The large accessory gearbox which dominates the whole port side of the motor is shown here. Slightly offset from the centre, along the bottom row of gear housings, is the plug for checking the level of and adding oil to the gearbox.

On the bottom is shown the inlet for the C-Stoff fuel pump.

Also, this illustration shows the electrical connections which deliver power from the aircraft systems to the electrical accessories of the motor.

Also, one can make out the motor identification plate, shining brightly on the top left hand corner of the side plate, just between the electrical cable and the fuel control connecting rod.
