A US Department of the Army 1954 dated technical manual titled TM 9-6147 "Panoramic Telescopes" in very good condition overall. US Department of the Army Technical Manual (TM) 9-6147 is an official military service and maintenance manual that provides instructions for operating, inspecting, and repairing panoramic telescopes (specifically the M12A7 series, including variants like M12A7C, M12A7H, and M12A7K). Panoramic telescopes are critical optical aiming devices primarily mounted on field artillery (e.g., howitzers and mortars).
