Article about: Hello everyone! My name is bill and I enjoy learning about WWII events and weapons. My dad and my father in law were both in WWII. I hope to get some help in identifying what is likely a war

What you have there is either a turbine or compressor blade from a jet engine. The serrations are a locking method whereby individual blades lock into a rotor disc. The serrated section is the blade root, in this case called a 'fir tree' root. It mates to a serrated groove in the rotor disc and is held in place by a side locking plate covering both serrations. There are a couple of other methods of locking blades, one is a dovetail fitting, the other simply has a hole in the blade root with a corresponding locking pin.
First guess is that it's from a British Armstrong/Bristol Siddeley Viper engine, circa 1953 onwards, an axial flow turbojet. It was mainly used in the BAC Jet Provost and Strikemaster as well as the Aermacchi MB-339 in RAF service.

Willie, thank you very much!
The photo you attached appears to be a perfect match to this item.
After the war, my father in law came back to the states and worked for Allison Engines in their jet manufacturing operation. This must be a souvenir from his days at Allison rather than from the war.
Thanks again!
