The Dooling Brothers are arguably the most well known of the Tether Car builders. Tom, Harris, and Russell Dooling began production with the Mercury Midget, also known as the First Series Front Drive, in 1939. It was followed by the Mercury Deluxe or Rear Drive in late 1939. The Streamliner, or Frog, was also released in 1939. In 1940 the last of the Mercury cars, the Second Series Front Drive and the smaller sized Pee Wee were introduced. After the War in 1946, the F car was put into production. The final production Dooling car was the Arrow, which came on the market in the Spring of 1948.
