RARE CRUFT LABORATORY MANUAL 1945 ARMY & NAVY ELECTRONICS EN FRANCE

Rare Cruft Laboratory Manual 1945 Army & Navy Electronics 500+ pages Harvard Loose bound 3-hole punch 4 1/4" thick book w/ mostly single sided pages. Was for Officers Training Course Engineering 270 of the Cruft Laboratory at Harvard Univ. Published 1945. Some of the material was originally classified as RESTRICTED by the US govt. Over 500 pages judging by the thickness (which is thicker than a ream of paper by quite a bit). Pages are not numbered sequentially so can't give a precise number. Includes schematics, troubleshooting, adjustment and experiment information on many U.S. Army and Navy receivers and transmitter that were used in WWII.  Also includes schematics for many lab test instruments used at that time. My photos shows pages that list some of the equipment covered in this large Laboratory Manual
