It is correct for possibly earlier and 109 E, 109 F and 109 G1/2 However, I suspect the F/G, as the serial number is high and it only has the tiny step for a minimal id tag, not the earlier larger one. Also, most photo's of 109 E and earlier seem to have the all-black tyres, the 1941/42 F/G seem to all have whitewalls.I'd say Battle of Britain era 109E.
Hi special ed,Would tailwheels have tread when mostly flown from grass fields?
That top item looks like the connection flex shaft to the gearing to change the prop pitch. Connects a VDM motor to the back gear plate behind the spinner.Hi ian,
Good thoughts, however not interrupter. These two parts work together in a propeller system..

Hi cammerjeff, One part is a reversable motor, the other is an electric contact limiting switch.It does look like a propeller pitch governor to me as well, is the top black part the speed sensor and the lower part the Pitch change servo to adjust the speed to the range selected?
Since Jumo props were hydraulic, I would proffer any German aircraft using the VDM props, which were mostly DB engined airframes. I am attaching two images, one from a DB603A and the other from a DB605, both having VDMs. I believe these may show the electric motor or mechanism for blade change, but I know you will know for certain. I suspect the Bf109? Thanks for the guess what test!Got to give you that one Tony! Extra points still available for the most famous aircraft that used this system?

Yes good shot. Now, what engine?
Hint: There are great clues on the impellor in the previous pic. Wink!

Very nice Tony. The 603 "water pump" is a steam extractor. These are found in many complex high-performance cooling systems and are designed to extract the steam from the solid water by centripetal force as the mix goes round the "snail", wet steam is allowed out of the central port and is fed into the header tanks or pipes.DB603 water pump
So, we are just a little off the mark with my parts! However, VDM prop control is the main thing here, often seen on DB engines but also on some earlier Junkers 210/211, and some radials inc BMW 132 and 801.
Here is a pic of my components on a contemporary famous fighter.

Hi Tony,So was this strictly on 109E's ? I had always thought this mechanism was underneath the engine just forward of the fuel injection pump. Found this image on the web which clearly shows it on a rebuild.
