USAF AN/GRR-7 Radio Receiving Set Technical Manual Binder – R-361/GR – 1952–1970

Original U.S. Air Force technical-manual binder containing multiple publications for the AN/GRR-7 Radio Receiving Set and its primary R-361/GR radio receiver. The AN/GRR-7 was a military communications receiving system used with associated antenna and radio equipment. 

The binder appears to contain several separate manuals and updated change sections, including:

• T.O. 31R2-2GRR7-3 — Overhaul Instructions for Radio Receiver R-361/GR and Antenna Assembly AT-197/GR, dated May 15, 1952, with Change 3 dated April 1, 1968
• T.O. 31R2-2GRR7-4 — Parts Catalog for Radio Receiver R-361/GR, dated May 1, 1952, with changes through December 15, 1970
• AN 16-30GRR7-2 — Service Instructions for Radio Set AN/GRR-7, dated November 1, 1952
• T.O. 31R2-2GRR7-26 — Preventive Maintenance Instructions, dated July 23, 1956
• T.O. 31R2-2GRR7-14 — Spare Parts List for Radio Receiving Set AN/GRR-7, dated July 2, 1954

The publications are housed in a period blue technical binder with a handwritten contents label. Visible manuals show age toning, edge wear, creasing, small tears, handwritten equipment references, and general handling wear. Some pages have updated change sheets incorporated. Completeness has not been verified page by page.

A substantial reference grouping for collectors of Cold War-era Air Force communications equipment, vacuum-tube radio receivers, military electronics, and original technical publications.
