You'll need to find an old Huret or Simplex. All modern triple
derailleurs have shaped outer plates and will either rub on the crank or
on the chain.

The critical clearance is between the outside of the outer chainwheel and the inside of the right crank. On my Stronglight 49d with TA rings it is 5.5 mm (just checked with stack of feeler gauges); it was the same with TA on TA. That ain't much, and I think I measured 7 mm for a Stronglight 99 (several months ago, don't remember exact figure). So, Peter is giving good advice. I could not get either an early Shimano DuraAce or a SunTour Cyclone to set up cleanly. Much to my surprise, a homely Campy record is doing fine. But, I'd still rather find a pretty Stronglight 99 crankset for the Hetchins...
