I have recently acquired a CWS tandem frame, but having spent quite a lot of time trawling through the various images on the www, have yet to see one either in an advert, or a photo of one. Head badge is a simple brass diamond shape, and the frame has braze-ons for a trivelox rear gear, but other than that its just a bare, but very light, frame.
Does anyone have any info on CWS's tandems at all?
