Yes, George, a nice one for sure! Like you, I'm surprised it hasn't sold more quickly, particularly where it is on this side of the Big Water.
I agree...that front hub look like it might be a dynohub. Fun to speculate.
There's a surprising number of Thorns in Florida but we typically don't hear too much from the owners. I may have corresponded with the owners of this one back in 2010 when I was contemplating my Sherpa purchase, but then again...this one looks newer than that.
Best wishes to seller and buyer alike.
All the best,
Dan.
