Listing is for ONE (1) Vintage USAF aircraft engine control wrench manufactured by Beech Aircraft Corp., Wichita, Kansas under USAF contract. This specialized aviation maintenance tool is identified as “Wrench Open End Engine Control” with Beech part number TS-859, matching the stamped TS-859 marking on the wrench itself. Multiple packages pictured to show variance in packaging.

The original military preservation wrappers remain with the tools. Packing varies as shown in photos; however, labels typically include inspection and acceptance dates circa 1950-1951 along with USAF stock and contract references. The long-offset dual-end configuration was designed for aircraft engine control linkage and rigging adjustments in confined engine compartment areas. Likely applications include throttle, mixture, carburetor, or propeller control linkage servicing on mid-century Beech military trainer and utility aircraft.

An excellent Korean War-era USAF aviation maintenance collectible with strong display appeal and clear documented provenance directly to Beech Aircraft Corporation.
