Vintage Aero Supply Mfg. Co. aircraft fuel control selector valve assembly, Assembly No. 14300. WWII-era four-port aviation fuel selector valve featuring heavy cast-metal construction, exposed selector-drive gear, original safety-wired hardware, screened internal port detail, and cast Patent No. 2164232 markings.

Research indicates this assembly is consistent with Aero Supply PK-4 fuel control selector valve assemblies referenced in wartime aeronautical fuel systems catalogs issued during WWII. Catalog references associate this valve family with several notable U.S. Navy aircraft including the Grumman F4F/FM Wildcat fighter series, TBF/TBM Avenger torpedo bombers, and PB2Y patrol bomber aircraft. Screenshots included for reference; however, catalogue is NOT INCLUDED WITH PURCHASE.

This example differs slightly from some catalog illustrations by using a geared selector-drive configuration rather than the four-prong yoke style shown in certain wartime diagrams, suggesting a possible alternate actuator or installation variation within the same valve family.

An exceptional display and restoration piece with outstanding mechanical and industrial appearance. Ideal for warbird collectors, WWII aviation historians, cockpit builders, restorers, or military aircraft museum display collections.
