1920

The Dart Blue “ J” of 1920 was available in two sizes — a 12-25 selling for $1,850, and a 15-30 model which was listed at $2,000. Both used a four-cylinder Buda engine, the 12-25 had a 4 1/4 x 5 1/2 inch bore and stroke, and the 15-30 used a 4 1/2 x 6-inch engine. With this exception, the chassis and other accessories were identical for both models. A water-type air cleaner was used; this was sometimes called an “air washer.”
