Pretty much all of the HO couplers are undersized for S scale unless you happen to model a prototype that used what is referred to as a 3/4 scale coupler... which is what the Walthers ProtoMax coupler SEEMS to be about right for (based only on photos I have seen of the ProtoMax). Central of Georgia early passenger car #2 (presently preserved at the CofG Roundhouse Complex in Savannah, GA) has a 1:1 example of one of these couplers. (See photo attachments)
Strangely, the ProtoMax seems to resemble this smaller coupler in some ways...

I seem to remember some discussion about a Walters coupler. I've also seen some people use the #5 instead of the S Scale one. Any particular reason for this beyond availability? Accurail make two sizes of HO couplers, has anyone tried to use the "larger" one in S? I've seen them used in On3 and they looked great, plus there is no spring. Any thoughts on this, John? Cheers.
