Mel, you are very quick in identifying the heritage of the aircraft.
The Bellanca Bimotor Transport was an eighteen-place civilian transport version of the Model 77-140/320 Junior Bomber prototype and seaplane. Designed in 1934, the Bimotor was equipped with the latest blind flying instruments of the day, and had oleo type undercarriage. She was powered by two Wright Cyclone 710-hp geared radials vs. the 715-hp motors of the Model 77. The Bimotor Transport's wing span was 76 feet vs. 77 feet of the Model 77, and an overall length of 44 feet, which was 4 feet longer than the Model 77. Given the wingspans of the aforementioned aircraft, and the fact that the "-320" of the Model 77 referred to the 32-foot long floats, perhaps Bellanca should have called the Bimotor the Model 76. You have control.
