As is often the case, I only get serious about answering my own
question AFTER I ask someone or some group the question.
A quick Google came up with <
http://lingua.mtsu.edu/chinese-computing/
statistics/char/list.php?Which=CL>, which was posted by Jun Da
(Classical Chinese Character Frequency List, 古汉语单字频率列表, Jun Da 笪骏
<

computing/statistics/>.
Also, Bruce Brooks' List is long out of print.
Thanks,
