Here's a pre-war Norton Chassis I sold to Sven some years ago. (Not SWD) Ron
A couple of observations Ron - the front lower sidecar fitting seems to be missing - I am not sure that the front springs used hangers to suspend the tie bar - my Model G sidecar chassis certainly did not have the hangers on the front springs - I am not sure that the rear sidecar fitting is original. I thought it would be the same as the SWD Big 4 rear sidecar fitting.
There's some parts missing from your pile now Ron!
Sven, the Big 4 chassis is totally different to the 16H type, Tony, I do have some parts of the chassis left maybe, but sold most of that 2 years ago. I do have a front brake plate for sale, if you need one, they are different from 16H.
Keith that first picture was taken before I'd made modifications to the front springs and removed the hangers and I also fitted the 4th attachment point. The rear fitting was just something I made up from parts I had, with the intention of replacing with a better part when it came along. But I decided that one Norton sidecar outfit was enough, especially as it opened up room for another bike!! Ron
