Hugh Hemphill just wrote me to say that he has just finished an additional page about their 1928 Durant belonging to the Texas Transportation Museum to their website.
Here is the link: http://www.txtransportationmuseum.org/DUR.htm
Their Durant-Star is an M2, Serial number E-3344. He has also begun work on his second book. The first one, published earlier this year, was about local railroad history. The new project is going to be about the arrival of automobiles and the evolving road networks. He said that he's going to make a point of finding out if Durants were sold in San Antonio and may even find an advert or two in the papers of the day.
I've also added a link to their website on our own Links Page under the "Friends of Durant Motors Automobile Club" section.
