Default Axial 120PS D270 "EDUL ZUG" propeller

Hi, has anyone seen a prop like this before? Diameter is 11 feet (335 cm), hub is just over 5" thick (13 cm). A couple numbers embossed on the front (serial and horsepower?) but nothing else. Curiously it has only six bolts. Found in the south-west of the Netherlands.

It's not common but certainly not unusual. It's hard to identify, particularly since the 6 bolt hole hub eliminates many of the early (WW1 era) engines. Even at 11 feet it's still a little smaller than most of the airship propellers.

The data block was located.

142...
Axial
Berlin
120PS D27....
TP11
EDUL ZUG (there is that magical word again where nobody knows what it is)

It was probably not measured correctly.

Very weird though, to see an Axial propeller with just six holes?

My current guess is that it belonged to an Albatros B.II with Argus As II engine.

"Edulzug" just means tractor propeller (vs. pusher). I presume that you've already figured out that the "PS" refers to horsepower (although stamped HP often doesn't match with currently listed engine HP for many engines.)

It's unfortunate that we've more or less lost Bob Gardner's input here. He understandably got tired of doing a lot of free research with not even a word of acknowledgment for his efforts from the poster asking the question. I share in his frustration, and we've discussed making this research a paid service instead of a voluntary effort.

Bob's books on German propellers have a lot of useful information in them, and I'll see if I can find any clues there.

Thanks very much!
I too have spent thousands of hours researching aviation stuff for others, I know what you mean.
