Recognition Manual Pages, Luftwaffe, of British RAF Aircraft
This is an interesting compilation of pages from a loose-leaf Recognition Manual of the WWII German Luftwaffe. The pages contain diagrams, silhouettes, photographs, and key information (in German) regarding about 30 aircraft in use by the British Royal Air Force during the early years of WWII, including those made by US manufacturers such as bomber B-17 and fighter P-40. It even includes aircraft which were obsolete by the time the war began, such as the US Douglas B-18.
The collection of pages measures ~9 inches tall and ~6 inches wide. Some pages are worn and have a tear or two. But it is a remarkable find nonetheless.
