Its main task was to provide the Royal Navy with navigational products and service, but since 1821 it has also sold charts to the public. The present chart was composed after Admiralty surveys of 1836-48 and 1911; it was first published in 1888 and saw several corrections up to 1934. - With a single fold. A few manuscript notes. With a stamp "Increase 50%" near lower right corner. Captioned in print and in a former collector's hand on verso. Slightly brownstained.
