German Propeller Identification Please

[johnnym]

Hello All,

I recently came across a prop with the following hub info and trying to determine what model/engine it's from:

Integral Propeller DRP N5630 - D 270 - S140 - 160 PS .. 6CYL

On the prop itself is written:

Geprüft P & W" "Stand 1280"

The measurements are:

Length 270 cm
diameter hub approx. 19 cm
inner diameter approx. 8.5 cm

No pictures at the moment.

Thanks,

John

Only my opinion, and not conclusive but:
The size suggests “early” propeller; the stamped words are evidence of German manufacture (Integral Propeller Co. had subsidiary companies in Britain, France and Germany); 160 PS and 6 CYL suggest Mercedes Dlll engine, WW1 era.
