The before tractor is owned by Bill Gardner (http://www.usedgravelys.com). It may be for sale, ask him.
The After tractor is a beauty owned by Bill Guthrie from West Virginia. It's one of the most perfect Gravelys I've ever seen. And it's not a restoration, it's completely original. This is what they looked on the show room floor. The pictures don't do it justice.
