T.O. No. 91-150JA-2, Erection and Maintenance Instructions for Army Model F-8 Airplane. Marked "Restricted". Partial manual (pp 1-12, 33-34, 39-40, 59-60, 77-78, 153-160) may be a revision or change notice but not marked as such. Never the less, the included pages have many of the interesting illustrations such as cutaways of entire aircraft, packing and jacking diagrams, engine mounts, fuel systems, camera locations and two very detailed cockpit drawings. Very good.
