I worked on one of those about 11yrs back. It was a 3 axle, 4 horse unit. Some guy brought it to the shop to have us clean up the fenders and respray the whole thing. I hope he replaced the boards inside, I wouldn't trust it with my horses...
It didn't look nearly as good as the pictures you posted.
