The chop was done by Tim Warneck at Retrolinear.
The legs come do come off via wingnuts and a few standard bolts. Below are some pictures of it's evolution. So it's not as fast a breakdown as it would be if you had folding industrial legs, but for me, where I'll only bring it out on special occasions AND be able to get it down my basement steps with hard turns, it's perfect. It takes about 10 minutes to put together, which really is pretty reasonable given the beauty of the organ. Really have to give Tim credit for an awesome design!
Needless to say, this thing is awesome. I couldn't recommend Retrolinear highly enough... for any of your vintage keys needs...
Fantastic job! Personally I would have chosen a wood color instead of black but that's just personal taste. I regret immensely selling the C-3 I used to have and keep going back and forth with the idea of getting a B-3 - the problem is that they are so huge. I sold my two-manual Viscount clone recently and was thinking of getting an XK-3c. I played one and was really impressed by it 
Nothing sounds like the real thing, but the XK-3c is really well designed
