On the first page, in the left column near the bottom, is the season first place in the Grand Prix open class for Chris Blum. Chris was my parts person at BMW of Marin in San Rafael, CA.
On the second page, right column is the dual win including Gerald Pels on a BMW in the open production class. Both riders came in with the same total points after the year of racing.
Both riders missed one race, so these results are even more impressive. They raced the same machine in both classes. Racing a production machine, and winning, in the GP class is quite impressive.
