OK, here's the pic!
When I rode my bike cross country with Bikecentennial in '76, I used these panniers. It was a family run operation that made great bags at the time. Mine were stolen with the bike I rode that summer later in the '70s. 8^(
Freshly cleaned and in great shape, here they are mounted on the Gordon. Wish they were blue, but just fine red. Now I have to find the handlebar bag to go with them, and I'll be back!
