The Jabro MKI was the first sports car creation by James Broadwell and Ed Alsbury. The name Jabro was formed from the first two letters of JAmes and the last three letters of BROadwell. James was the president of Broadwell Distributing Company. It was created in 1957 and was in instant success. A Mark II and Mark III soon followed. The Mark II was a lighter version while the Mark III was the smaller version. The engine was typically a Crosley unit with a 2.54 inch bore, 2.36 stroke, and inline valves. Output was in the neighborhood of 65 horsepower. The engine was often fitted with Dell Orto-25 semi-downdraft carburetors. The chassis was constructed of multi-tube birdcage spaceframe while the body was of aluminum and fiberglass construction.
The cars were simple with only essential items. The instrument was also only essentials, with an oil temperature, oil pressure, and tachometer gauge.
In 1956 James decided to create a car for the H-Modified class. The design started from a wooden model he had whittled. He then bought the running gear from a 1949 Crosley with the intent of using those components for his racer, which he dubbed the Jabro Jr. By Daniel Vaughan | Sep 2007
