Maintenance Handbook Radar Set AN/MPS-4

Original early Cold War U.S. Navy technical maintenance handbook for the Radar Set AN/MPS-4, marked NAVSHIPS 91373.3. The title page identifies this as a maintenance handbook reproducing Sections 6 and 7 of the complete instruction book NAVSHIPS 91373. The manual was produced for the Navy Department by Hazeltine Electronics Corporation and carries the original “Restricted” classification markings on the front, back, and title page.

This is a desirable radar/electronics reference for collectors of U.S. Navy radar, Cold War electronics, military communications equipment, and technical manuals. The AN/MPS-4 appears in U.S. Navy electronics manual listings from the period, and NAVSHIPS 91373.3 is specifically listed as an AN/MPS-4 manual reference.  

The book has a heavy black hard cover with white stamped front cover text and a screw-post/binder style spine. Condition appears very good overall for age, with light edge wear, minor scuffing to the covers, age toning to the title page, and some expected handling/storage wear. The interior title page is clean and legible, with the contract number and approval/change dates visible. A strong display and research piece, especially when paired with AN/MPS-4 radar components or other NAVSHIPS radar manuals.
