Built in 1912, the 2-3 seat B-3 and B-4 had a wooden hull covered with galvanized iron sheeting. A 1914 version incorporated streamlining, and 1915 model was a three place “luxury cruiser” with a mahogany hull.
In 1914, the Thomas Company advertised aviation for sport, war and business. Their earlier models, the B-4 and B-5 were used as trainers for civilian pilots seeking thrills, speed and fortune.
Three or four were built.

A tandem two-seat primary trainer, the THK-15 was an updated Magister, made of metal, and with a cockpit canopy.

The THK-5 was a twin-engine aircraft developed in Turkey as an air ambulance. First flying in 1945, it was a conventional, low-wing cantilever monoplane of wooden construction throughout. The main units of the tailwheel undercarriage retracted into the wing-mounted engine nacelles and the THK-5 could carry two stretcher cases plus a medical attendant.
This was followed in production by a six-seat utility transport version designated THK-5A and three examples of an improved version of the 5A designated THK-10. A single example of the type was exported, sold to Denmark.
On September 6, 1951 THK-5A serial number 503 sold to Denmark was put into service with registration OY-ACK. The aircraft, which was used as air ambulance under the name TYRKEN (TURK) until logging 961 hours and 20 minutes. In 1960 it was resold and used by air taxi companies. On 18 November 1961 the airplane suffered a landing accident and was withdrawn to a children’s park in Lagunen. The wreck was eventually scrapped.
In total 13 were built.
When THK was taken over by MKEK, this was one of the designs selected for further work. However, although the designation MKEK-5 was allocated, nothing further came of this.
