Granville Brothers R-1 Supersportster Replica
The "Gee Bee" Supersportster R-1 was built in Springfield, MA. (Of note, the "Gee Bee" stands for Granville Brothers.) Flown by Jimmie Doolittle, it set a new world land plane speed record of 296 mph and went on a few days later to win the 1932 Thompson Trophy Race at an speed of over 252 mph.
The Granville's donated their plans to the New England Air Museum stating that they would be flattered if we saw fit to replicate their airplane, but stipulated that we never fly it and never loan the plans to anyone who wanted to build a flying replica. With this in mind and a lot of help from Howell "Pete" Miller, the R-1's designer, the museum built this plane using as closely as possible 1932 vintage materials and work methods. An engine was located whose serial number is only two digits away from the original, and the rare propeller was donated by its manufacturer, Howard Smith.
