Need some information about a Pratt & Whitney engine.

 

 

-The P & W R 2800-21 was used on what aircraft?

-It's SerN° is 42-126159. Was this engine produced during the war?

-What does the abbreviation "WRAD" means?

-Is "4-23-45" a production date?

-For what stands "TT763" on the engine?

The R-2800-21 was used on several models of P47's according to Graham Whites book on the R-2800.

 

I can't find a good picture of a -21 dataplate so is there any chance you can post a picture of the data plates on the engine in question? WRAD could be an overhaul facility, 4-23-45 could be a overhaul date and TT763 could indicate that the engine had 763 hours total time when it was overhauled.

 

If you have access to the engine logs, that might help too.

Yep, the -21 was used on razorback P-47Ds and I would think that the 4-23-45 date was an overhaul date like M1Garandy said.

Depots during WWII would normally stamp their ID, engine serial no., total time, and overhaul date on nose case or front section of main case. Same info could also be stenciled on nose case. Cylinders would have total time pencil etched on skirt or would be marked "NEW" if a new cylinder was installed. WRAD became WRAMA (Air Material Activity) in the 1950's and is now WR-ALC (Air Logistics Center).
