I've ordered these spokes,
DT Swiss Aerolite Spoke 2.0mm Bladed 278mm Straight Pull Black, with the hopes I can re-shape the head into the flattened "T" head of the original Roval spokes.
Sorry about the poor focus.
In the meantime, I'm cleaning, polishing, and lubing the Shimano 600 AX RD
clubman so generously sent me from Nova Scotia, and I've mounted new Vittoria Corsa tubulars on the original Dura Ace AX hub/Fiamme Ergal rim wheelset. Hopefully I'll have the Lotus back on the road soon.
