As Bubba says, I would spare the poor wife. If you have a copy of the original For Sale Post I would copy it and the Browning Work Order and send them along with a letter stating your case to the Attorney General in Texas and ask how he recommends you proceed. Ask if there are other instances like yours involving this dude.
A letter from the AG to this seller may enlighten him to your intent to get this resolved in an appropriate fashion without costing you a bundle. In New York State we have a Small Claims Court where you can go for small amounts such as $1,000 without large filing fees, attorney and the complexities of a higher court. Good Luck.
