An Irish surveyor’s compass (dated 1816) of the King George III era
Dimension: length 17” (43cm), compass diam. 6 ¼”(16cm)
with fixing bar to locate it on a plane table. It was made by John Burke and retailed by Walker & Son, 17 Temple Bar, Dublin. Very nice engraving on the whole silvered compass bottom, and with its brass cover. Beautiful original patina.
John Burke as a maker is not known to historian of Science, but a William Burke from Belfast produced instruments in the first half of 19th (Clifton). .
