God I hate bikeforums. I had posted the SVG years ago but I guess it was purged for some reason.
I get PMs for it all the time and do not have enough "points" to reply to them.

DIAF bike forums .... bikes.StackExchange will win in the end.

Anywho, I'll see if I can dig the SVG up and reattach it, and mirror somewhere else.
My Vent-Noir was stolen on tour in 2005, so I can't remeasure. Le sigh..
