Maybe for a while, Eric, but I think most of the Raleigh Pros used the standard TTT stem, ignoring the slight mismatch, meaning yoy simply had to tighten down the bar clamp more. We've discussed this a few times before, and I think that was the consensus. This is the first time anyone raised the possibility of a 25.4 version of the TTT, although it's always possible.

I know that many 1970's Raleigh Professionals came equipped with 3ttt Record stems and GB "Map of England" engraved bars. I have a set of those bars and the clamping area measures just shy of 25.4 so my guess to your question is that 3ttt made stems with the larger size opening for their own bars but also with a smaller 25.4 opening for standard ISO bars.
