Need Help for German Propeller Identification!

[Oliver]

Hi Everybody!
I'm just new here. I live north of Berlin, Germany. I own a old propeller (maybe WW1) from the propeller-factory "Niendorf- Luckenwalde" south of Berlin.
Can someone of you please help me to find out on which Airplane this propeller was mounted on???
Unfortunately it has been cutted in the center - as you see on the Photo's.
There are following Numbers/Datas stamped on the wooden surface:
"5026"
"200PS 300D" (> maybe means 200 horsepower and 3 meters diameter!)
"176 St"

On another place is stamped:
"Geprüft" (= Proved)
"FLZ" (maybe FLugZeug = Airplane)
"STAND" ( maybe "Airbase")
"1320"
I will be very thankful for any help!!! Best Regards - Oliver Simon

Guten Morgen Herr Simon,

Your data translates as;

5026 The Gebrüder Niendorf serial number
200PS A Benz engine of 200 Pferdestärke (German horse power)
300D Durchmesser (Diameter) 300cm
176 St Steigung (Pitch) 176cm
Geprüft FLZ proved under test at the Flugzeugmeisterie test center
STAND 1320 Stand is short for Standdrehzahl, meaning speed of revolution in the context of a test. Here 1320 indicates the speed in rpm to which the prop was tested.

The prop was used on either a Gotha G IV or the Halberstadt C V.

Gebrüder Niendorf GmbH was at 20 Mozartstrasse, Luckenwalde, Brandenburg, South of Berlin. The last time I was there the factory still existed.

The brothers Karl and Herman Niendorf established their Pianofabrik (Piano Factory) in 1896 in Luckenwalde in Brandenburg about 50 miles southwest of Berlin. Most of their pianos went to export and became highly esteemed. They still are. At the start of the war they lost most of their export markets and it was probably a relief when they were co-opted by the Government into propeller production in 1915.

Mit freundliche Grüssen,

Bob
