1950's Space Age 83" Experimental 2-Bladed Polished Helicopter Rotor Airplane Propeller

Description

This extraordinary polished aluminum propeller is a true one-of-a-kind aviation artifact, originally acquired from the New England Air Museum in its unrestored condition. Believed to have been developed by one of the golden era's premier aerospace innovators - Pratt & Whitney, Sikorsky, Raytheon, or Kaman - this piece carries an authenticated experimental designation stamped directly into its brass hub: "EXP USE ONLY." Dating to the 1940s-1950s Space Age, it represents a rare window into the experimental aviation programs that defined a generation of aerospace engineering.

After careful disassembly, cleaning, and hand-sanding, the propeller has been brought to a stunning high-mirror aluminum finish, crowned with a custom dome spinner cap for an unmistakably futuristic silhouette. Whether mounted in a loft, executive office, hangar, or aviation collection, this piece commands attention as both a museum-quality historical relic and a breathtaking work of industrial art.

Key Features

• Authenticated Experimental Status: Hub bears the stamped marking "EXP USE ONLY" on the brass section, confirming its experimental aerospace origins.
• New England Air Museum Provenance: Originally acquired directly from the New England Air Museum, sourced from donations by top aerospace firms including Pratt & Whitney, Sikorsky, Raytheon, and Kaman.
• High-Mirror Aluminum Finish: Completely disassembled, cleaned, sanded, and polished to a brilliant mirror-like reflective finish - a full professional transformation.
• Custom Dome Spinner Cap: A purpose-built dome spinner cap was added to complete the sleek, space-age aesthetic and enhance the futuristic profile.
• 83" Overall Length: An imposing display piece spanning 83 inches tip to tip, with 41-inch blades measuring 5.5 inches at their widest point.
• Vintage FAFNIR Bearings: Era confirmed by original internal FAFNIR Company bearings and hand-stamped identification numbers, placing manufacture in the 1940s-1950s.
• Unique Hub & Blade Stampings: Multiple original stampings include A70708MP, B12, SK14446, SER# 8, MP70736, AF35704, and AF35728 - each a direct link to its experimental aerospace history.
• Wall Mount Ready: Designed for wall mounting via the hub using a standard lag bolt - no special hardware required beyond basic installation.
• All-Aluminum Construction: Lightweight for its size at 38 lbs, with blades secured to the hub via set screws for a clean, stable display.
• 38 lb Weight / 10.5" Depth: Hub base to spinner top measures 10.5 inches, giving the piece impressive dimensional presence on any wall.

Why You'll Love It

There are very few artifacts that bridge the worlds of aerospace history and contemporary art the way this propeller does. Its documented experimental origins, New England Air Museum provenance, and hand-stamped markings make it verifiably authentic - not a reproduction, not a decorative replica, but a genuine piece of mid-century aerospace engineering. The mirror-polished finish elevates it from relic to showpiece, catching light from across a room and drawing every eye to it instantly.

Collectors, aviation enthusiasts, architects, and design professionals will all find something compelling here - a conversation piece that carries real history. It's equally at home in an aviation museum, a high-end loft, a corporate lobby, or a dedicated collector's gallery. Pieces like this rarely surface on the open market, and with its one-of-a-kind experimental designation, this propeller represents an irreplaceable chapter in American aerospace innovation.
