Thomas Towle was an engineer that had been involved with many early aircraft designs.
The wings were all metal with internal stiffeners, rather than ribs, based loosely on the Ford Trimotor, which Towle worked on previously.
The twin Wright R-540 engines sat on small pylons on top of the shoulder mounted wing.
[2][3] Two floats were mounted directly below the engine pylons which incorporated the hydraulically actuated landing gear.
[6] The aircraft appears to have been rebuilt as a Towle TA-2 and was reported to have visited Lympne Airport, Kent, United Kingdom in February 1930.
