Does anyone have any information about this organization?

By "googling" I came up with this information:

NATIONAL SPRINT CAR HALL OF FAME & MUSEUM
TOM CHERRY by Don Anderson & Dave Argabright
http://sprintcarhof.com/FileGet.aspx?ID=128

He was instrumental, along with Dutch Hurst and others, in forming the Mutual Racing Association in Muncie, Indiana in 1938, Tom's hometown. Running "roaring roadsters", the group raced at the Muncie Steeplechase (literally, a steeplechase course) in 1939. By 1940, they began racing on the tight paved oval at Mt. Lawn Speedway near New Castle, Indiana. That was the year of Tom's first Mutual championship.

The Mt. Lawn website has an entire section devoted to the Mutual Racing Association. You can find it at www.mtlawn.com/MRA/Page.html

I know that in the fall of 1960 the membership of the Mutual Racing Association was combined with another club to form UMRA. I also know that the MRA had been sanctioning three-quarter midget racing for several years.

Had the MRA evolved from roaring roadsters to TQ's? Or was the MRA similar to USAC with different divisions, one of which was TQ's?

Does anyone know where I might be able to find statistics on any TQ races sanctioned by the MRA, or any other organizations?

Thanks,
Sandy
