A stunning unused Instrument.
This is a Mk3 Campbell Stokes sunshine recorder signed by the manufacturer, Negretti & Zambra, London. This instrument was made for the British Meteorological Office & plated accordingly but not given a reference as it was never released from Negretti stores & it has never been used. This particular instrument is for Temperate latitudes with ‘LAT 45’ – 65’ engraved on the top of the bowl. Please contact me for more pics. A quantity of seasonal recording cards will be supplied.
