Dear Jim,
I have just published a small book 'A Study of the Quadrant' that does have a
few pages about the Gunter device. It has just 6 pages describing their use and
functions with various photographs.
Your book on 'The Astrolabe' was very useful to me in producing my book. Thank
you.
, please reply off the Mailing List.
Thanks in advance for your kind help.
