I borrowed the full volume through inter-library loan when I was in college 10 years ago. I was pretty excited to look through it, but I didn’t find much data that wasn’t already widely known. The ECL production trends book offers a much more detailed look at production totals, though a lot of it is hard to understand without an understanding of the ECL codes, and some of the years/models went missing at some point..
