Valerie Davey is developing a website on Kus Kuhn and the firm of the same name. http://www.guskuhn.net
I note one of their customers was Anthony Valantine, who played the nastly German captain in BBC tv Colditz. The duelling scar under the eye was actually the result of an impact with a kerb which left the imprint of his goggles!
He was a customer of ours at Geoff Dodkin the Velo dealer in East Sheen and used to bring the latest flame into the shop and out the back door, where the boys used to rate them on a scale of 1 to 10 - many 10.5 were registered I can tell you.
Happy days!
