1923 Mercedes ex-Indy racer, being re-fitted by Zumbach Motors with a four-cyclinder, 220-ci, twin-camshaft supercharged Miller engine. The Mercedes had performed dismally at Indianapolis because of poor handling. The rework was done for McClure Halley at a cost of almost $20,000. The completed car was entered in ARCA competition in 1934 and 1935, and also entered for the 1936 Vanderbilt Cup Race. The modifications apparently did not help the handling situation, and the vehicle never made it to the starting line of any race. The car is known as “Haley’s Comet”, and it now resides in Bob McConnell’s collection in Ohio.
