I remember seeing Dragwaye run in several of its guises, and it always impressed, perhaps because it was so different to other 2 wheelers, and to me it kindof underlines how people back then were prepared so much more to try "outside the box" solutions to going quicker/faster and sometimes having some success.
What I haven't seen before is that pencilled in streamliner outline on the line drawing. What a pity that was never built, it looks neat and would have been great for events like the Elvington records weekend, and I suspect the machine may well have acheived a greater fame or at least a higher "memory factor" with that disguising its novel approach.
