Robert S. Butler posted:Bob - there are so many additions/corrections to be made to the accessory section of the AF Wide Gauge book that about the only thing I've found it good for is a simple listing of accessory numbers and possibly some sort of timeline. My guess is that if there had been a second edition that section would have seen a major revamping.
Agreed. I attempted to say something along the same lines, but more gently. 
However, folks reading through this thread and absorbing this topic on a first pass should be made aware of Mr. Schuweiler's scholarship of the time. The table on page 122 is very good. One's alternative back then was to pick through many issues of The Collector. Given that it was 32 years ago, the chaos inherent to the subject, and the resulting incomplete nature of the accessories portion of the book, Section 8 Tunnels, on AFMCo. tunnels is actually still quite serviceable, but in need of a revamp, as you say. Errors of omission rather than commission. That's why it is so wonderful to see NWL initiate and seriously flesh out the topic of AF prewar tunnel variations in this thread.
Respectfully,
Bob
