Japanese Aircraft Performance & Characteristics TAIC Manual No. 1 (RAF)
This is an original WWII-era intelligence manual published by the Technical Air Intelligence Center of the US Navy covering the latest information regarding aircraft of the Japanese Army and Navy. Also included is information on Japanese aircraft engines, armament, and radio equipment.
It is in good condition given its age. There is a wax paper cover over its front and back. This one appears to have been sent to the British Royal Air Force per its handwritten marking on the cover.
