JPW integral spinner

Hi to all!

This is my first post! I'm writing from Italy and I'm a lon-time aeronautical collector. I own a german JPW spinner. Is decorated with the classical JPW logo with circled letters and wing, and the iron cross, both on decal and on both of one side's blades.

I was thinking that was (as the one showed on your site database) a German J.P.W. - Gnome 100 H.P. spinner, but on a closer inspection, my spinner is quite different, by design and marking.

I would like to know what kind of propeller is, by which airplane has been made and any information you may have on it!

Thanks in advance!

Best, Dr1

The spinner is complete, of course, and is cut only in photo, because I'm not be able to take a complete pic of it! Its length is 280 cm (110,32 inch)...

Very nice looking propeller.

Can you read the stampings and post them? It is difficult to read them in the photographs. Sometimes a magnifying glass and oblique lighting will help make it clearer.

Greetings! Welcome to the forum.

JPW indicates the Jntegral Propellerwerke, originally a subsidiary of the French Integrale Co that was taken into German ownership when WW1 broke out.

This decal dates your propeller from September 1914 to Summer 1916. The markings on your prop are not in the German style. They are in an Italian style and I don't know what they mean. As your propeller originally had six bolt holes it is probably from a 100ps or 120ps Mercedes engine used on aircraft in Germany such as the Albatros B II. Please measure the length of your propeller. I expect it is 2700mm or 2750mm.

With kind regards,

Bob

Hallo Bob!

Nice to hear from you! And thanks for your reply!

You're thinking right! The length is 2800mm. You say that should have six bolt holes... but my propeller had nine holes. Therefore it cannot been used on Albatros?

And why there's italian marking on a german propeller? It was found in Italy, brought home by a vet, but I thought it was war booty from a german airplane downed by our pilots..

Best, Dr1
