I saw (on-line) this interesting sun compass for sale by auction
this coming November 20th. I have not seen anything like it. Other
scientific instruments, clocks, sundials for sale at same auction.
I doubt I will bid on it. -Bill http://www.skinnerinc.com/asp/fullcatalogue.asp?salelot=2527M++++363+&refno=++874110 Lot 363
