| The first production variant powered by a vertically mounted 175hp Franklin 6ALV-335 six-cylinder engine. The enclosed cabin, seating two side-by-side, featured two car-like doors. A total of 78 Model 47Bs (including 47B-3) were produced. Very few Model 47Bs survive today (c/n 11 registered N11HU, 57/N1575, 58/N138B and 70/N150B). In 1989, one exam-ple (c/n 36, N116B), was restored to flying condition by Douglas D. Daigle of Santa Ana, California.

| Kathy Devlin, kd1921(@)verizon.net, 25.08.2009 I have a photo dated in the late 1940's of one of these helicopters. It is pictured hovering over a parked New Jersey State Police vehicle and and motorcycle. It has in big letters, HAT. Any idea what that means and what they may have been doing? |
