Arnold, the other guy on volume six with me was Frank Petruzzo (sp), who has since passed away, quite a few years ago now. He was quite the standard gauge Blue Comet specialist. I recently heard a story from a friend of mine who knew Frank about one such Blue Comet adventure at a train show.
Regarding the dates on the videos, I believed Tom released one volume per year starting in 1987, and ending with volume six in 1993. The 2004 date is probably a re- copyright date when the series was re-released on DVD.
