In the 50,s i had a model 7 1953 with single downtube frame and swinging arm painted silver and have not been able to find out a lot. I still have the book that came with it and some pages have been glued in on the rear suspension. The book was supplied with the bike when sold new. Was it just made up for the export market and were they sent to New Zealand. Have had some interesting discussions and wondered if someone could explain. Thankyou i do have a photo taken on a box brownie.
