1934 Adler Trumpf Junior Type 1E

Adler was a classic German automobile and motorcycle manufacturer from 1900 until 1957. Adler is German for eagle.
The Adler factory produced bicycles, typewriters, and motorcycles in addition to cars. Before World War I, the company used De Dion two- and four-cylinder engines in cars that ranged from 1032 cc to 9081 cc; beginning in 1902, they used their own engines as well. These cars, driven by Erwin Kleyer, Otto (both sons of the company founder, Heinrich Kleyer) and by Alfred Theves won many sporting events. In the 1920s, Karl Irion raced many Adlers; popular models of the period included the 2298 cc, 1550 cc, and 4700 cc four-cylinders and the 2580 cc six-cylinders. Many of the Standard Adler models, built between 1927 and 1934, featured Gropius and Neuss coachwork. These had 2916 cc six-cylinder engines and 3887 cc eight-cylinder engines.
