Wright/Cyclone Engine Instructional Manuals

[Bodes]

Forum Members, I came across a couple USAAF wright/cyclone engine military instructional manuals.....I believe these engines were used on the B-17's as well as other aircraft....The manuals are in good condition with "classified" stamped on the covers.....Inside are fold out colorized sectioned engine drawings of the nine cylinder radial engines.....Also included are drawings of sectioned Holley carbs....They are dated 1941 & 1942....The guy wants an offer but not sure how much these are worth....Any thoughts appreciated as usual....Bodes
