This is an authentic WWII-era War Department Technical Manual, Aircraft Engines, TM1-405, published in January 1945. The 83-page manual covers the basics of design and operation of piston engines in use by the US armed forces during WWII.
It is in very good condition given its age. Pages are yellowing as expected but appear to be all intact without tears.
