I didn't intend for it to reopen vigourous debate, but now that I'm taken to task a bit let me finally clarify why, and it isn't a matter of oversensitivity.
However, 1.25" gauge is 0 Gauge and has been for 110 years or so. It didn't need to get redesignated when Cronkhite pushed 1.1875" as Q gauge, so I don't see why it needs redesignated Ow5 because 1.177" is (only one element of) P48. Since its inventor coined it just to take the piss out of the rest of the O Scalers as he held court in the bar at Indy (Many of you will recognise who I mean. Grin!), I choose not to use it in a business setting as long as there are people who remember and still resent it.
Its not that I personally have a stake, nor is it a matter of oversensitivity. Right or wrong, purposely anymore or not, the use doesn't do the perception of the P48 community from outside any good at all. Just perceptions, and sure there shouldn't be preconceptions and all that, but there are. So, the perception (whether true or not;its a real world) of whether welcoming or elitist affects the P48 community positively or negatively. I prefer to affect it positively (if we affect it at all) so I get to the same place.
Not telling anyone how to run their business, just explaining why I chose and stick with the path we follow, so don't take me wrong (especially Jay). Just some history to consider is all that's offered from here.
To your points, Bob and Rich, 0 gauge is defined as 1.25" gauge and has nothing to do with scale, number of rails, or how big they might be. Where P48 is arguably the ultimate expression of American O
Scale, it is not O
gauge; we are talking about gauge. With respect to gauge, whether its scale or tinplate is really moot, and doesn't need yet another obfuscation; the difference is quite painfully obvious beyond pickup methodology. Its 2-rail or three-rail, else we also have to become similarly pedantic and come up with a trophy for the outside third people and the stud-pickup people so everyone gets one. Grin!
Having chucked that grenade into the crowd, I shall now run away, because it doesn't matter to me personally since I'm in 7mm and we have our own issues of scale versus gauge versus profile standards.
