And, yes, if you're diligent (which I am kicking myself for not being), these can still come up NOS on eBay:
As rare (and way cooler to some of us!) than those old Clement Setas!).
I hope to post new pix of my '67 Holdsworth Super Mistral tomorrow which I have just reshod with a new 27 x 1 1/4 wire-on wheelset: Dunlop Special Lightweight rims, Schwinn Super Record 27 x 1 HPs (their clone of the Dunlops), classic 32/40 drilling and Campagnolo "no Record" large-flange hubs. She looks, to me, way better than with the 700 sew-up wheelset I originally fitted. But I'll let you all be the judge of that!
