Well, I turned the adjustors around, as advised by the list. This frankly makes more sense than the Campy design in terms of ease of adjustment, although the Campys are less likely to vibrate loose. While I was at it, though, I removed the Simplex (I assume) adjustor screws from the drilled and threaded Simplex DO's on the Follis 172. I tried these in the Huret DOs to see if perhaps the Huret DOs were threaded for some French-demension adjustors. The adjustors from the Follis seem to have the same thread as Campy adjustors or the Huret adjustors. All three types insert through the Huret DOs without engaging, and require the little crescent shaped nut inside the Huert DO to engage them.
Anyone know if Simplex actually made Campy-type adjustors for the threaded Simplex DOs? Or did they just thread the DOs to take Campy or Campy clone adjustors, which could be what I have?
This would suggest the Huret DOs may be unthreaded. Or if threaded, they require a larger adjustor screw than any I have yet discovered. Anyone ever seen dropout adjustor screws with a diameter larger than the Campy ones?

Actually, that makes more sense than the Campy design, in that it's much easier to adjust them when the screw heads are to the rear. Of course, with the Campy design, if the heads were to the rear, you would need some sort of removable cap at the front end to retain the spring. The current Campy caps might work for this, but if they were in contact with the wheel, it would be better for them to have flat tops rather than domed ones.

Just found my 1973 Huret catalog, it shows the cresent shaped plastic "nut" in the rear of the dropout with the screw head in the rear (outside side of the dropout) the end of the screw locates the axle. Charlie Petry ,between Cochranville+Jennersville PA USA
