Dick (and all), It is my view that "3-Point" gauges are more suited for use in hand-laying track than they are for checking the gauge of existing track. A gauge for hand-laying was my focus when I designed those gauge(s) I posted about recently (see here again : http://www.trainweb.org/seaboard/ODDSTUFF/MultiRailGauge.gif), and this might be why you (Dick) didn't understand my design. And I have to admit that I failed to mention my focus. So... my bad.
As for a gauge that is more suited for CHECKING THE GAUGE of existing track, I feel that something very similar to, if not identical to the HO NMRA Gauge (see here : http://www.walthers.com/exec/productinfo/98-1) is what we really need in S. But I understand that such a gauge, of course, would only be suited to SCALE modelers.

Each rail size (125, 100, 83, 70) has a different width railhead. And sometimes you will find different widths within the same nominal rail size (O scale code 100 vs. S scale code 100, for example). A three-point gauge must be made for a specific railhead width. That's just too many combinations for a practical commercial product. The best way (for me, at least) to gauge rail on curves, if spreading out the gauge on curves is what you want to do, is to use the NASG track gauge makimum measurement -- where the gauge just drops in off its little shelf.
