Despite undergoing major redesign in an attempt to improve performance and handling it failed to obtain any orders.

[3] In 1924, Thomas designed a single-engined two-seat observation aircraft, the TM-24, in a further attempt to find success with all-metal construction.

Additional auxiliary tail surfaces were mounted on the aircraft's fin, above the main tailplane, which acted as trim tabs.

The aircraft was powered by a 440 horsepower (330 kW) Curtiss D12 water-cooled V12 engine driving a two-bladed propeller and cooled by radiators located in fairings in the lower wing-roots.

While testing indicated that performance was good, the aircraft's landing speed was considered too high, and its rudder was masked if the observer stood up in his cockpit to use his machine gun.
