please help identify: aircraft prop blade - ww2 or later?

Hey forum folks,

I don't know whom else to ask about this, so maybe you'll be so kind and have an answer?

I inherited this ..well.." home made artsy candle holder" after my grandma died some years ago..
.. no one else wanted it and theres no one left to ask since when it sat in the attic in her house in Germany or who made it.. it's made from a propeller blade and very old.

my question ... what aircraft is this from? ww2 or newer? worth keeping?
I did google but couldn't come up with something..
its about 1m / 3.3 feet long and seems to be iron/ steel..

thank you.

anyone?

The only recommendation I can make is to consult Welcome to Aviation Archaeology and have a look at the various inspection stamps as several are visible in your photo.

From that you may find a manufacturer. If you cannot find any that help, or better still find one that may help, contact them with your photos and what you have learned from their site.
