OK. The history of the Heine propeller company is well documented and can be found on Wikipedia: https://de.m.wikipedia.org/wiki/Propellerwerk_Heine “Waidmannslust” refers to the area of Berlin where the Heine factory was located.

The markings on the hub are hard to read in your photographs but I think I can make out the word “RHONE” underneath “110 PS”.
This suggests to me that this propeller was made to fit the LeRhone 9J engine, of 110 HP, which was built in Germany under licence by Oberusel during WW1. It is said that the Germans also made use of captured French-built LeRhone engines, so this might have been made for one of them..

These engines were fitted to a variety of aircraft in German service, most famously the Fokker DR1 Triplane.

Any chance you could post some high-resolution photos showing all of the markings on the propeller hub?

Also, if you could measure and post the dimensions of:

Hub thickness
Hub diameter
Bolt hole size
Bolt circle diameter
Centre bore diameter (if possible)

That would be very helpful in confirming the identification.

I’m still thinking LeRhone: The bolt circle diameter is spot on and the other measurements within a plausible margin of error.

What do the experts on here think?

I have been looking with a magnifying glass and the data can be read as
110 PS
RHONE
D263
H222
HEINE
N27688
Waidmannlust
Berlin
What’s strange is that the lettering contains gold paint.
Is this common?
Greetings
Geert
I would be very gratefull if someone could determine the airplane this was used on and also the date of the propeller

All of the specifications and markings on your propeller (apart from serial number, which is consistent with the same era) match exactly with one which was positively identified by Bob Gardner on this forum in 2014.
You may remember that you were interested in buying it?

Therefore, I can say with certainty that your propeller is from:

Aircraft: Fokker DR. 1
Date: 1917 or 1918

It’s a long time ago. But now seeing the topic I’ll remember it.
It’s indeed almost the same data on it.
The other one must have been sold to another person
Never heard of it again.
Now I was just looking for a propeller who’s smaller than 255cm for hanging on a wall and I came across this one.
It must be a coincidence that it was the same data because this one is shortened to 251cm.
Thxs a lot for all the info!!!!
Greetings,
Geert

Any time I see gold or white lettering I just assume that has been done by a subsequent owner, not the factory or any mechanics.

I have an original Garuda propeller which has silver paint which fills the stamped letters. It is in original condition. It has never been restored or refinished. I can even see marks which were either left by a tooth of a toothing plane, or more likely a nick in the blade of a draw knife. This mark was not sanded before the propeller left the factory. Achim Engels uses gold paint for his reproduction Axial propeller stamps and I'm sure I have studied original German propellers which have gold paint. I will see if I can find some photos.
