It bridged the gap between the fabric-covered biplanes of the 1930s and the all-metal, low-wing monoplane fighters that would define the Second World War. This archive brings together the surviving original factory and military documentation for the P-36 platform in a single, structured collection.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003eArchive Manifest\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreliminary Handbook of Operation and Service Instructions — Model P-36A Pursuit Airplane\u003c\/strong\u003e\u003cbr\u003eCurtiss Aeroplane Division, Curtiss-Wright Corporation, Buffalo, N.Y.\u003cbr\u003eContract W535 A.C. 10136 — Specification 64193\u003cbr\u003ePublished by Authority of the Chief of the Air Corps, Materiel Division, Field Service Section, Wright Field, Dayton, Ohio\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandbook of Operation and Flight Instructions — Models P-36A and P-36C Pursuit Airplanes\u003c\/strong\u003e\u003cbr\u003eTechnical Order No. 01-25CB-1\u003cbr\u003eCurtiss Aeroplane Division, Curtiss-Wright Corporation, Buffalo, N.Y.\u003cbr\u003eContract W535 AC-10136 — Specification Type 98-605, Model 98-605-1 (P-36A) \/ Model 98-605-2 (P-36C)\u003cbr\u003eDated: February 15, 1940\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandbook of Service Instructions — R-1830 Series Aircraft Engines\u003c\/strong\u003e\u003cbr\u003eTechnical Order No. 02-10CB-2\u003cbr\u003ePublished by Authority of the Commanding General, Army Air Forces, Headquarters, Air Service Command, Patterson Field, Fairfield, Ohio\u003cbr\u003eDated: February 25, 1942 — Revised March 20, 1943\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetail Specifications for Curtiss Hawk 75-A Airplane\u003c\/strong\u003e (No. 6895-A)\u003cbr\u003eCurtiss-Wright Corporation · Curtiss Aeroplane Division · Export Sales Division\u003cbr\u003e30 Rockefeller Plaza, New York City, U.S.A. — Cable Address: \"AEROEXCO\"\u003cbr\u003eSubtitle: Single Engine Pursuit\u003cbr\u003e\u003cem\u003eProvenance: Finnish Air Force (Käyttötoimisto) library stamp and Mercantile dealer stamp — a rare export-chain provenance trail documenting the document's journey from the Curtiss Export Sales Division to the Finnish Air Force.\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003eAerodynamic Design \u0026amp;
