Approximately 35p plus around 13 pullout diagram/charts at the back. The book covers fuel and oil systems; aeroplane controls; engine controls; handling; operating data; emergency procedures etc. The diagrams include the instrument panel, hydraulics, fuel system, turret hydraulics etc. Each copy was marked as 'Confidential', covered by the official secrets act and had an individual reference number, 8231 in this case. The cover is sound but soiled,creased and dog-eared at the edges with some card absent on the spine.
