I live for the CABE
Does any period account of his racing mention the marque(s) he used?
I don't think there is anything like that. Basically you have to see what year the picture is of him on a bike and figure out what bike he's on.
I have put together my own timeline of his racing bikes periodically but not easy. He raced in Europe on several different bikes and here
he was famous on the Iver Johnson. But, he rode so many bikes that I'm still waiting for someone to put together the timeline of bikes like
I have done with Eddie Bald. I can pretty well tell you every bike Bald rode year to year from 1893 to 1903. Waiting on a Taylor aficionado !!
