I have looked for other photos from this time period trying to determine the standard mounting procedure used for the vibrator on these special Buick’s. This is the only one I have found that resemble each other. Does this mean these two racers are one in the same? That would be interesting if proven but I will not make that judgment. Notice the Remy unit (below)
on another 1909 Buick racer in the Indianapolis museum. It has what looks like bronze mounting straps. Some of the company’s making coil units at that time are: K-W, Duplex, Lemke, Kingston, Heinze, Remy, Jefferson Electric, Detroit Coil, Atwater Kent, Bosch, Auto Coil, National and Perkins.
