A mid-20th-century desk accessory featuring a four-engine bomber aircraft model, identified by visual characteristics as a Boeing B-29 Superfortress. The item is constructed of cast white metal with a heavily worn gold-tone or brass wash. The aircraft is mounted via a curved, C-shaped support arm to a shield-shaped ashtray base. The base features a textured, rocky surface and two cigarette rests along the perimeter. The propellers are represented by four flat, circular metal discs. No maker's marks or signatures are visible on the aircraft or base.
