Vintage Ingersoll-Rand Multi-Vane pneumatic industrial tool with long-reach shaft assembly and reversible vane motor configuration. Marked “Ingersoll-Rand Multi-Vane” and “Made in U.S.A.” with additional number “923393” present on the handle assembly. Features a lightweight aircraft-style aluminum body, pistol grip trigger control, extended reach shaft, and specialized end attachment consistent with mid-century aerospace or industrial assembly tooling.

Exact application has not been confirmed, but this appears to be a specialized aircraft or factory maintenance/assembly pneumatic tool from the WWII–1950s era. The reversible control and long-reach configuration suggest use for confined-access industrial work, possibly aircraft production, maintenance, drilling, fastening, or assembly operations. An unusual and visually striking piece of vintage American industrial tooling with excellent display and collector appeal.
