I should have been more specific about d'Imperio's work.
The structure and direction of the research reported by, and expanded upon by d'Imperio was determined by William Friedman's two study-groups. d'Imperio's book was published in 1978, when the National Security Agency printed it. Some of her references to Brumaugh and to Tiltman are dated in the 70s, but I take those as filling a couple of gaps.
Others may feel differently.

I think it includes answers to these questions.
Thanks for asking them.
