Among the approximately 150 cars expected at this year’s Put-in-Bay Sports Car Races are five mini-racers. Four are H-Modifieds — the featured class at this event — meeting the SCCA specifications for this class (500-750cc engines, two seats, room for a spare wheel, and a door); the fifth is a Berkeley, a car whose 492cc engine would allow it to run as an I-Modified, an even smaller racing class.
The car pictured above is a Jabro Mk III H-Mod. James Broadwell built several versions of Jabros in St. Louis, Missouri. Customers could choose anything from plans to a finished car. The versions, Mk I, Mk II, and Mk III were popular among H-Mod racers, though it’s unclear just how many cars were built.
The Mk III is often described as a “mini Birdcage Maserati,” featuring a lightweight, mini-tube space frame with a fiberglass body. Cars were built with a variety of engines, from Crosley to Saab.
The green and white No. 99 car that will be at Put-in-Bay is powered by a 2-stroke, 3-cylinder Saab engine – and has the sound and speed to prove it.
The 2021 Put-In-Bay Vintage Sports Car Races & Reunion organized by Put-In-Bay Road Race Reunion will be held Tuesday through Friday, September 21-24, on the Put-in-Bay (Ohio) Airport Course.
