Smile German ww1 prop id

Hello,
I recently aquired a German ww1 propeller.
It is 3000mm lenght.
On the back of the hub is mentioned 3000,185,and (3285 or 3235) hard to read.
Oh the side of the hub there's
......PROPELLER
B.....
200PS
D.....
One of the blades is stamped with ausgewogen
There are 9 layers of mahony/ash wood.
It is full lenght.
Special is that the prop end edges are fitted with copper sheeting.
It appears to be original
Other feature is that the propblades are clockwise (so engine turning in other direction or pusher engine)
After a little research:
Engine probably benz
The D mentioned is probably EDELDRUK


Please more info??
Greetz

Greetings Geertse,

Please add some photographs of your prop so that we might see it, and some of the data as well. It is often difficult to read these data on old props and we might be able to find some clues there.

So far, your data indicates;
D possibly Druck or Druk indicating a pusher installation
Brass tips; can also indicate a pusher or a seaplane
D300 Durchmesser (diameter) 300 cm
Ausgewogen balanced
200ps a Benz engine of 200hp

The use of mahogany and ash suggests it was made before 1917-18.

The only prop that I know of which roughly fits these details was made by Imperial for the Freidrichshafen G II.

With kind regards,

Bob

I'll take pictures this weekend.
I'm sure it's a pusher type prop.
But not one for the 260ps engine.
So there are not a lot of airplanes from the pusher type with the 200ps engine I suppose?
Greetings,

At the moment, only one that I know of.

The word before propeller and the word after B... should help.

Bob

On what basis? The direction of rotation doesn't necessarily dictate traction vs. pusher configuration.

Because you can read druk on the hub.
So that must be a pusher otherwise it's zug.
I've read that the copper sheeting is mostly used for seaplanes and pusher planes for german props.

Sorry, I didn't realize you could read DRUK.

You can still find it on the early prop site. I think there
were a few pictures but some details have been removed
by the owner later. Initially the prop was offered for sale
on different sites for 4000 but she removed the price after
a few days.

Regards
Gino
