The Number 9 Offset is forged on the original HB die. I repeat until I get the offending nut here in Llanberis North Wales where we forge them I'd prefer not to speculate further, as that is what most of this is, speculation. I will gladly post the results up when ready.
Just as an aside Rockclimbing.com might be doing a feature on DMM in the future which would be good as you will be able to have verification of what I have tried to explain from a neutral source. Unless any of you guys find yourself over here in which case I'll gladly show you around personally.
