Sorry, it's off topic this one but I got a real sense of de ja vu when I saw the new website header photo. This is my 1927 Raleigh 500cc Model 21 at a VMCC trial at Post Hill, Leeds, c1970. At least I didn't have to wear a back pack and 303!
Michiel W, is this the same as the Raleigh you are working on at the moment?
