Thanks for the response......... I've only found a bit here and there about the Lone Star. It appears that the Piedmont Motor Car Co, Lynchburg, Va. produced them for a couple of years (1919 - 1920?). I'm not sure about the numbers because all that was different was the radiator emblem between the Piedmont, Bush, and the Lone Star. There was a new dealer building, 4 stories, built in EL Paso as noted in an ad dated March 16, 1921 that was touted as "state of the art" I wish I had more info, but as of now I am still in the search mode.
