Henson, the original Piedmont. This livery was used from 1983 to 1987. As far as I can tell, Henson used these Short (Bros. of Belfast) SD3-30s from around 1979 to 1990. This one went to Alleghany then was exported in ’91 to Canada, whence it had come. This is another Mary Jayne’s Railroad Specialties postcards, airline series.
