I have done that (plus a few of my others) - thanks for the heads up!

as far as cranks go, I've always liked the ones based on the 50.4mm bolt circle. The T.A. Cyclotouriste is an example, with other manufacturers making equivalent parts. I've got a modern SunXCD version of this on my Hetchins (to get some hill climbing gears)....

At the last Classic Rendezvous gathering, there were a few Hetchins on display. These sported a Campy Record, a 3 arm steel crank, and a Cyclotouriste style crank. The 3 arm cranks are certainly a suitable style for that vintage. The more modern alloy versions still look pretty nice and are probably easier to find. T.A. made a nice one (seen on Raleigh Competitions for a while), and the Campy Gran Sport is good too (also on the Raleigh Competition G.S.)
