I have had only had a little time to peruse my autographed copy of the book. Seems that David was on his way to Prototype Rails 2016 meet in Coco Beach and had stopped in town to visit his wife's relatives. Just a long mile from me. Small world.
In my examination I saw more pickle and vinegar cars than I've seen in searches on the internet. He also has lists of companies and the cars that they owned. Looks like I can accurately renumber/repaint those K-Line and Lionel cars. Maybe I'll cause a run on them.
He also shows diagrams with pictures of vinegar and pickle plants. Many are small enough to model with little or no compression.
Overall I have a very positive first impression.
