TM9-2662 BINAURAL INST M2. Binaural training instrument M2 dated 1941. This VERY interesting manual covers the machine used to test and train men in the use of sound locators and other devices then both ears are needed.
Something coming from WWI but really never used in WWII and that makes this a hard manual to find. 21 Pages.
