The blueprint explicitly identifies the aircraft as a 'GRUMMAN S2F-2'. Grumman Aerospace Corporation's primary design, engineering, and manufacturing facilities were located in Bethpage, New York. This is the most probable point of origin for this technical document. The coordinates point to the Grumman Memorial Park, which is on the site of the former plant.

The Grumman S2F-2 Tracker was an anti-submarine warfare aircraft used by the United States Navy. Documents like this would have been essential at naval air stations where the aircraft were tested, maintained, and operated. Naval Air Station Patuxent River is the U.S. Navy's principal test and evaluation station for naval aircraft, making it a highly probable location for such technical data to be stored and used.

The document is stamped 'CONFIDENTIAL', indicating it was a classified military document. After declassification, such historical technical records are often transferred to the National Archives and Records Administration (NARA) for preservation. The NARA facility in College Park, Maryland (Archives II), is the primary repository for modern military and government records, making it a plausible current location for this document.
