It is quite often called a Cord L29 Aero but in fact it was a one-off built in Belgium and is a Röhr 8F Streamline Saloon. The car came back from the USA to it's "hometown" Ober-Ramstadt (home of the Röhr works) a number of years ago and is now painted in its original colour dark brown. There was a Cord L29 Speedster (boat tail) https://www.stahlsauto.com/automobiles/1931-cord-l-29-lagrande-speedster-legend-of-the-lost-cord/
