My dyslexia lets me down here. To search you need to spell. That is a problem with made up words. Scootersean, or a version of that, asked to be notified when I finally got the, I believe to be, ex RAC Watsonian Bambox MkII together in one place. I at last have managed to do this, finding the last bits over the Mushy.
It has a GRP body, sectioned into compartments with ply bonded in. The large rectangular lid is hinged to one long edge, lock on the other, and has a tubular rack on top. The body is mounted to a double rail chassis using two wood spacers (It might be that it will run an 8 inch wheel on a common hub with the body mounted lower). The mounting for the bike is a classic Watsonian steel disc with four holes in it. To date the bike mount I thought I had has not surfaced and I think I must have let it go with the last sidecar I sold, prior to getting this one. I have the suspension mount, hub and assembly, pretty simple arrangement. The hub mounts a 10 inch wheel that is to all intents and purposes an Isetta wheel. The sidecar has front, rear and parking light.
The condition is requiring restoration. The GRP has one clipped corner on the lower wheel arch, a small hole in the floor and stress cracking and minor impact damage from stones. The steel has all had surface rust but is solid and will go again. Minor wood rot, will go again. The original paint looks consistent with this being an RAC sidecar in blue. It has been over painted in white.
A hard thing to value as I suspect it is either very rare, or unique. With a well chosen Scooter, or Motorcycle, it will be a show stealer restored. I was going to put it on a Hienkel, will not fit a Prior as they are not ideal handed for British chairs. Its not going to happen. Better it finds a person who can create the most out of a nice bit of tackle.
It should be ready to view from next weekend 11/12th - busy rally weekend, builders allowing. Pic to come, as it might be interesting even if you do not want a sidecar.
