Re:
I am sure I have one in my workshop. PM me with your address and I can post it. I see you are a Rotrax fan, as am I. (Concours 1954; Super Course 1949; Vel d'Hiv 1951 and possibly a La Premiere from 1957)
Could you send me pictures of your Rotraxs for comparison? If they are large frames and you ever think of selling I would be keen!
All the best, Geofffrey
