Let us not forget:
Model 61: Bell's proposed tandem rotor anti-submarine helicopter (1953).
Model 201: An experimental Army H-13 with a Continental XT51 turbine engine (merely a license-built Turbomeca Artouste) in 1955.
Model 533: Modified model 204 with wings, two Continental J-69 engines on either side of the fuselage, and a variable-tilt rotor mast! (1962)
Model 207: This lookalike predecessor of the AH-1 series was actually based on the model 47/H-13 powertrain and airframe (1963)
Model 309: KingCobra (1971).
Model 409: The 409/YAH-63 was Bell's competitive entry to the AAH (Advanced Attack Helicopter) competition won by the Hughes AH-64 Apache.
Model 222: Two-blade, twin-engine, civilian (no military counterpart) executive transport (1974).
Model 230: Basically a 222 with Allison C-30's instead of the awful Lycoming LTS-101's. (1991)
Model 430: Longer cabin, four-blade version of the 230 and specifically designed for shipboard operations by a single, very low-time pilot. (1994)
Model 406: Basically a 206B (short) airframe with a four-blade rotor. More popularly known as the OH-58D. (1983)
Model 400 Twin Ranger: Fugly-looking four-blade 206L (narrow-cabin) with a ring tail back end and two Allison C-20R's. (1983)
And those were just some of the ones that they actually built.
