My dad and I were there on Thursday.
On our last tour of the Swap Meet area, I saw those also.
The CS was chugging away on the back end of a trailer, so I could not get to close to see much. I took a couple of pictures, I am not sure how they will turn out, I have not downloaded them off the camera. The "Omega" twin was in the back of a pick up truck.
Sadly, they were both out of my price range, or I would be the proud owner of a piece of history.
