History

Between 1911 and 1922
O.W. Timm built several aircraft with varying success before he founded, in 1922, the O.W. Timm Aircraft Company. Timm manufactured six models of a parasol design, the Collegiate. In 1934 Otto and his brother
Wally Timm
Wally Timm (August 8, 1896 – April 29, 1978) was an American aircraft designer, pilot and manufacturer.
Early life
Wally Timm was born in Lakefield, Minnesota, and with his family moved to Windom, Minnesota. He worked closely alongside his brot ...
joined to form a new company named the Timm Airplane Company to produce the Timm T-S140, a high wing twin engine aircraft using new features developed at
NACA such as flaps and tricycle landing gear. Wally Timm formed his own Glendale based aviation company later on, the Wally Timm Inc.
The company developed a "plastic" material made of resin and wood similar to the

process. The Duramold and Haskelite process was first developed in 1937. Followed by
Gene Vidal's Weldwood and later the Aeromold process. The Aeromold process differs in that it is baked at a low at cutting and forming, and for fusing together sections after the resins are added.
In 1939, at the onset of World War II, the company operated as the Timm Aircraft Corporation, building the PT160K trainer prototype using the aeromold process. By 1941, the U.S Navy ordered the aeromold
N2T-1 with a production run reaching 260 aircraft along with other small aircraft parts made of the aeromold process. Profits increased to $70,000 from $240 the year prior. The company also license-built 436 of the
CG-4A glider used by allied troops. A Plywood construction variant, the CG-4B was developed by Timm in case of material shortages, but did not go into production.
