The Spartan 7W Executive is a five-place all metal monoplane that features retractable landing gear and a luxurious interior. The Executive was designed to be fast and comfortable with extensive insulation to lower cabin noise levels. Executives were used for business and personal transportation, and set a new standard for speed and style.

The overall level of technology and performance was comparable to the best fighter airplanes of the day, and this was reflected in a high cost – a factory-new Executive cost $23,500 in 1937.
