Bill,
I still have the mast. You cannot have it (well, maybe, for the right price). I have a friend who used to build DN masts and he looked at it and thought we could make a pretty good back-up mast from it.
It broke closer to the base than the top. It is a Hall spar and is mostly unidirectional carbon in the area, so most of the breaks are multiple splits going vertically, lots of vertical splits. I thought about making trophies out of the tube (I already removed all the hardware and have purchased another Hall spar to build into a spare mast), but after talking to my friend, I may repair the damaged spar, reassemble it for a spare, and sell my undamaged spare Hall spar. I haven't decided yet.
