I'm not sure, but this looks an awful lot like the one that I read about on FSB, about the time I posted that I was doing mine. The guy had been at it for some time before I started, and was still at it after I had finished. All kinds of pictures of welding and fab work being done to get it in there. I guess if it is the same one, and he's selling it, he either didn't like the way it turned out, or has financial problems. I can't imagine all that work he did and then getting rid of it.
