Assistance in dating a Turbocharger Impeller

Radial Ronny · May 27, 2024

Turbocharger Impeller from a General Electric turbo. Identifying the part is fairly simple from the technical manuals, but has anyone any clues as to a production date from the numbers and stamps? Thanks for any assistance.

Sorry, I don't know any single Turbocharger Impellers.

She'll want to know where you are going to take her out to eat.

Is this new term, perhaps one replacing the very popular "304"?

The 21 week of 1949 is a guess.
Is it nickle alloy?

Why do you guess week 21 ?

Thanks for your reply. Not sure about that date, but anything is possible I guess.
The impeller would appear to be an aluminum alloy material.
