It's a Duesy LbNA #69304

Duesenberg Automobile & Motors Company, Inc. (sometimes referred to as "Duesy") was an American manufacturer of race cars and luxury automobiles. It was founded in Des Moines, Iowa, United States by brothers August and Frederick Duesenberg where they built bicycles and sports cars.[ The brothers later moved their operations to Indianapolis, Indiana, home of the Indianapolis Motor Speedway and built outstanding automobiles. They were self-taught engineers and built many experimental cars. Duesenberg cars were considered some of the very best cars of the time, and were built entirely by hand. In 1914, Eddie Rickenbacker drove a "Duesy" to finish in 10th place at the Indianapolis 500, and Duesenberg won the race in 1924, 1925, and 1927. The fledgling company sidestepped into aviation engine manufacturing when Colonel R.C. Bolling and his commission acquired a license to produce the Bugatti U-16 for the U.S. Army Air Service. The end of World War I stopped this project before it could ever mature. In 1921, Duesenberg provided the pace car for the Indy 500, driven by Fred Duesenberg. In 1923, Jimmy Murphy became the first American to win the French Grand Prix when he drove a Duesenberg to victory at Le Mans. In late 1926, E.L. Cord added Duesenberg to his Auburn Automobile Company. With the market for expensive luxury cars severely undercut by the Depression, Duesenberg folded in 1937.
