Thank you Steve, Nick and Bruce! You answered my question. I think there is definitely some material in the "R" reports that would be both interesting and useful, but sometimes we just have to step back, sigh, and say that now old and very shop-worn cliché, "it's just a bridge too far." My archive-crawling days are over and were 15 years ago.

BTW, I am almost certain that there is mention of the "R" reports in these and the dozens of other books on the subject as well as in the hundreds of articles published in Cryptologia, International Journal of Intelligence and Counterintelligence, Intelligence and National Security, and other scholarly journals.
