Pilot Handbook, T.O. 1H-3(C)C-1, 27 December 1967. Approx 100 pp plus numerous supplements. Included in the front are telex interim operational supplements on the KB-18 Strike Camera, the Rescue Hoist and the AM-146 Terrain Implantation Bomb (used to mine the Ho Chi Minh trail). This manual differs from the 1965 version in that there are sections on armor plating and the M-60 machine gun mounts. This is a Vietnam combat-used manual from a dear friend who flew this aircraft on black-ops missions by Task Force Alpha into Laos from Nakhon Phanom RTAFB, Thailand. Housed in the desireable red leatherette 9-ring binder; very good condition.
