Older than the "Classics", which came out in 1984. This was for the 737-100 and -200, and the 707, before them. I practiced it (once) in a KC-135, more than three decades ago. Not sure when the instructions disappeared, but I don't think they were ever in the 'Classic' manuals.
We need a good nickname for the first generation 737s. For that matter, the term "next-gen", or NG is pretty outdated, at this point.
