Tarquin Publications of Stradbroke, Diss IP21 5JP, England,
publish a splendid cut-out book of <Sundials and Timedials>, by Gerald
Jenkins and Magdalen Bear (ISBN 0 906212 59 6) - very cheap! I believe
the same publisher offers an Astrolabe in the same format.
At the other extreme is Humphrey Cole's astrolabe (and other
mathematical instruments) which I had the good fortune to see on Saturday
in a special exhibition at the British Museum (room 69a).
