Well, you can see it, because I bought it. I find it one of the the most unusual bicycles I've ever encountered. I have some (bad) pictures up at
I will try to get better ones today.
Anyway, I get the impression from the frame that Les knew it was a special project between that father and son, as the lugwork--you can see--is more ornate than anything I've seen on a tandem. Full 531 tube set, and but for a hefty rear wheel assembly including the drag brake (also a very unusual piece) it seems to be nice and light. I repacked the wheels when I got it and the boys got some good miles in on her, as the hubs are pretty well worn out. I have a lovely NEW set of Maxi-car hubs that I'm building up for it.
The frame obviously needs a respray. The decals have worn off, but the outlines are still there, and they are in that funky art nouveau font.
I am very interested in joining, or starting, a Les Rigden society. There is very little about him anywhere, and judging by this frame, and the couple of restorations of his I've seen on the classic lightweights web site, he was a master who deserves greater appreciation.
