Hi Franc
“Bellanca’s Golden Age” recently published by Alan and Drina Abel has the following about the Bellanca 77-140 Bomber:
” In 1934-35 Bellanca also built the Bellanca 77-140 Bomber. While the US Army rejected the bomber, several were exported and saw service in Columbia, South America. Intended primarily as a patrol bomber, it carried a crew of four – pilot, navigator / bombardier and two gunners. The bomber was built as a landplane and a seaplane. Two 715-hp Wright Cyclone engines which provided a maximum speed of 165mph, powered the bomber. The initial rate of climb was 950 fpm and the range at maximum overload was 1,500 miles.”
The book has a picture of a floatplane version of the bomber. It is high winged with the aerofoil section 3/4 span strut arrangement of the Aircruiser origins are very evident. It has an open-topped nose turret. It has a single fin but with finlets, presumably to give increased directional control in view of the floats fitted.
Sorry I can’t scan in the picture , the book is of the perfect bound type. If you want to get a copy it is ISBN1-891118-46-3 and is published by Wind Canyon Books Inc. They have a website: http://www.windcanyonbooks.com.
Hope this helps.
