I hadn't noticed how uncommon GHD M-Cs were until you pointed it out. For what it's worth, my records indicate I've only seen 2, and they're both to the high end of the range - 46- and 47-. Compared to 29 W-P of roughly the same size range, that is odd indeed. I will certainly let you know if I find another one (and probably keep it while I'm at it)
