70th Anniversary of the signing of the Pacific Phosphate Co agreement, the stamp shows us Chinese coolies and mine pinnacles in 1905;

50th Anniversary of British Phosphate Commissioners, the stamp shows us an electric phosphate train, barges and merchant ship in 1920. Not any information on the cargo vessel. The loading with barges stopped after the first cantilever crane was placed.

5th Anniversary Nauru Phosphate Corp which shows us modern ore extraction one of the cantilevers and a modern bulk carrier loading in 1970. I believe she is one of the Nauru Pacific Line of Nauru. It is not so clear but the funnel looks that she belongs to this company. The Nauru Pacific Line went out of business in the early 1990s. Could not identify the bulk carrier.
