It's the engine and propeller manuals that involve the R-2800 that bring me down to the B-26 and A-26.
Yes, the USAAF used some other multi-engined stuff with those big round engines, but the other guide/manual involves medium bombers.
Note there's some handwritten stuff in here, too, which gives it provenance.
