This Admiralty chart is a 1981 edition of the South China Sea - Southern Portion - Western Sheet nautical chart. It includes parts of Borneo & Indonesia.
It is a beautifully detailed chart first published in 1881, therefore this is an updated version of an 100-year old chart. The detail is stunning.
It has been plotted by the previous owner - a sailor and you can see his/her route in pencil.
Old charts are hard to come by as once out of production, retailers are required to return stock to be replaced with new editions.
measures approx 72cm across by 110cm high
