1913: Frank C and Fred M Wallace, Bettendorf IA. USA
In pre-WW1 the Davenport Mfg Co had been building a Blackhawk Model A, and this apparently was either an offshoot or a development of that aircraft when the Wallace Bros acquired the holdings of Davenport Co in 1919, then bought a tract of land to establish Wallace Field.
1919-36: Wallace Brothers Flying Field.
The Wallace Brothers produced a conversion of a war-surplus Thomas-Morse S-1 with an uncowled OX-5.
The brothers were involved in the construction of the first three Central States Monocoupes, and worked with Folkerts and Luscombe, as well.
