I went and Googled it, that's where I got the link. Looks similar to my Danish ACAP. Half leaves in the rear, progressive coils up front, rigid frame. I do like the quick tub change out feature on the Watsonians.
and the famous sidecar race Steve English has a big website at www.steveenglish.com, wherein there is a "vintage classic where are they now?" section with lots of info on racing and building 16" wheel sitters and kneelers, and old F2 outfits. Also I am sure everyone here has seen the advrider "hacks" forum, some very good info and some long converations about building and setting up sidecar combinations, mostly on modern bikes but good info anyway.
also, there is a Steib Group on Yahoo, just looking through the photo archives is a treat and instructive- even though most of the bikes are BMWs, the pictures of frames and connecting parts are applicable to all bikes. The site has a number of photos of the old Malcolm Atrill Vincent-Steib "The Fast Lady". Atrill was a great engineer and his machine was an inspiration to me when I was young, built to the very highest standards.
