Indeed. Kingswood. Dad "came by" a pair of forks from the Douggie factory. They were probably experimental, basically two tubes with approx 6" leading links set in rubber. They were hanging around the workshop, so I took the girder forks off a 16H Norton and put the tubed jobbies on. Total failure. Speed wobble at about 35MPH. I used to do a lot of back to the drawing board. Still do. BTW, Here's Henry on his Douglas.
