B-29 Superfortress Mechanics Handbooks (2)

Here are two pocket reference manuals for mechanics servicing the WW B-29 Superfortress Bomber. One 70+ page handbook, measuring ~ 5 inches by ~6 inches, was printed in Nov 1944 and reviews the basic mechanical preventive maintenance checks and lists the technical orders for all other procedures and systems.  The second (blue), measuring ~4 inches by ~7 inches, is a 38-page photocopy covering basic troubleshooting.

This listing is for both pocketbooks.
