Found my trooper, yesterday! You follow lead, after lead, and good things happen. He recognized the property tag number, instantly, as they wrote it some many times. He said there was no doubt that it was his:
Unit A-41. He has an in service picture with him in it, the original plates, and high speed certification, still.

Many stories shared, and to be shared. I hope to get him behind the wheel again, when he comes to see it in May. I am as excited as a little kid at Christmas time.
