Can somone help to identify this blade (spitfire)

[AlainR]

Hello,
I've received this blade (gift) without any information.
Some of the numbers are not readable.
Thanks in advance for your support !!

Not sure of the aircraft, but the blade is a left-hand rotation blade so not for a standard merlin engine, more likely for a Griffon engine. You can confirm the blade rotation by looking at the Sensenich fix pitch in the background, as Sensenich do not manufacture an aluminum propeller with a left-hand rotation.

It looks to be a standard Rotol blade from a left hand tractor unit. So a twin or multi engined aircraft. OR a late Spitfire Mk18 or 21. OR something like a Typhoon or Tempest maybe. Too many options. More research using the serial RA-973 will provide the answer.
