* Update * The car is a circa 1904 to 1906 American Mercedes and the following readers correctly identified it: Ariejan Bos, Stefan Marjoram, and Dave Biggins.
Joe Jagersberger, a well-known early racer and riding mechanic, is posed above in an uncommon circa 1904-1907 automobile that appears to be wearing custom coachwork. We are going to use it to test our knowledgeable readers who we are confident will be able to identify it. Send us a comment telling us what make, model and year you believe it is, and we will reveal the results on Friday morning. In the meantime, you can learn more about Jagersberger and the RAJO Ford racing parts he later manufactured here on The Old Motor. The photo is courtesy of racing historian Kem Robertson.
