My feeling is that it is not a Phoenix, although it is a while since I looked at one. You don't know that it is nitrided unless you have evidence. I would measure it to check it is standard size, and assuming you are not using shell bearings see whether it might come in at -5 thou. The usual -10 thou is to allow for ovality and grooves which arrive with long use.
