German-born automotive manufacturer, 1877 - 1932. TLS signed 'F. S. Duesenberg,' on two 8.5 x 11 sheets of Duesenberg, Inc. letterhead, August 9, 1930. Interesting content with reference to automotive innovation. In part: 'I sent you a letter and a blueprint of the supercharger showing the general details that I had promised you to use in connection with your little motor. At that time you mentioned that you would like to send me one of these little motors. Of course I am very much interested in any motor that will turn over 40,000 r.p.m., which is about the speed that we used on this impeller. It took about 60 h. p. to run it.' In fine condition, with a rusty partial paper clip impression to the upper left corner of the first page and light creasing to the right margin. COA John Reznikoff/PSA/DNA and RRAuction COA.
