Provenance
Evans bought it from Percy Webster, his
      main London dealer, in 1911. Although Hispano-Moorish in
      style, and equipped with plates covering a wide range of
      latitudes from 25° to 60° (in five-degree steps), the
      existence of specific plates for 48° and 52° suggest it was
      originally made for someone based in Paris and/or London.
