Of course it sold... they go quick when an SBA with 100 holes is listed at $500. I've sold them between $800-$1,200, $800 being the norm.
The dimensions are:
13 feet long
6' 6" high without the beacon
29" wide
I have three more to sell. But, I won't be selling them for $500 now that I have a little space to work with. I would take $600 for the next one though.
