Help finding data on ISDE winners over the years
Long story short, I'm trying to put together an econometric model for manufacturer financial performance following big race wins (yes, this is what I do for fun when my bike's on the other side of the continent). Info on which manufacturers won Dakar and Baja 1000 (my other two samples) in given years was pretty easy to find but I can't find a source that tells me what manufacturers won the International Six Days Enduro (formerly ISD Trials) in which years. Alternatively, what make of bike the national teams were riding when they won in given years. I could hunt down articles one by one (e.g. "in 1983 so-and-so won on a Husqvarna so-and-so...") but that would take quite a while for thirty years or so!
I'm Googling my butt off but if any of you have any pointers on where to look for these results, I'd be very grateful!
