Cold War U.S. Navy NAVSHIPS 91213 TS-545/UP Echo Box Radar Test Equipment Instruction Manual (Restricted)

Original U.S. Navy Bureau of Ships Restricted instruction manual for the TS-545/UP Echo Box, designated NAVSHIPS 91213. Published for the operation and maintenance of the TS-545/UP radar test equipment, this manual was produced by the Johnson Service Company of Milwaukee, Wisconsin, under multiple Navy contracts.

The title page shows the manual was approved by the Bureau of Ships on 22 June 1949, with official Change 2 (16 February 1951) and Change 3 (5 September 1951) incorporated, making this a desirable updated post-WWII/early Cold War technical reference.

The manual retains its original gray flexible binder-style cover and indexed tab pages. It is an excellent addition for collectors of U.S. Navy radar equipment, military electronics, Cold War technology, and NAVSHIPS technical manuals.
