Bob Hall, who had recently split with the Granville Brothers of Gee Bee fame, decided to form his own new aircraft company at Bowles-Agawam Field across the Connecticut River from where the Granvilles had their shop. Bob Hall had originally served the Granvilles as chief engineer, test pilot and draftsman. But after a heated dispute with Zantford Granville over race plane design, he decided to go it alone and build his own speed planes. This new group would be known as Springfield Aircraft, Inc. With two firm orders in his hand, Bob Hall had leased a corner of the main hangar at Bowles Agawam Field where work began early in 1932 on the two never to be forgotten Hall racers.
