Hello Peter:
You almost “made my day”. I’ve been using H. O. 208 tables recently,
and I’m tired of using John Letcher’s book. I was hoping I would find H.O. 208
in your listing. Did I miss it?
Original Sixth edition H.O. 208 tables are no longer low cost or easily
found. Only a few choices on Amazon or Abe books. I’ve almost resigned myself to
photo copying the “208” tables and binding them myself. Oh well..... I’ll
keep looking. If anyone has an extra copy I would be happy to purchase it.
Please contact me via bpennino.ce@charter.net.
Have a good day.
Bruce

7-place cylindricalslide rule
Just to respond briefly to the recent messages on haversine tables:
there's a nice resource for historical math and astronomy tables called LOCOMAT
available here:
http://locomat.loria.fr/
http://locomat.loria.fr/
including digital reproductions of many of the classic tables. The
"census" link has a very long list, with nautical almanacs listed near the end
of the page for almost every year and country of origin. Links are
provided to digital copies at Google Books and gallica.bnf.fr. (Shameless plug: the
maintainer/curator, Denis Roegel, includes a link to my analysis and scans of
the Briggs 1617 log table. woot!)
He also has a recent paper (March 2015) on a 7-place cylindrical slide rule
of length 2000 meters, with descriptions of previous cylindrical rules such as
the Fuller, Otis King, Thacher, and several others I'd never heard of:

Several thousand pages of scales included. Some assembly
required.
