SummaryNo 9 Mark III telescope transportation box used by Australian Army and Navy heavy long range artillery units during the Second World War for telescope storage. Telescopic sighting instruments were used by long range heavy artillery units of the Australian Army and Navy during the Second World War for coastal defence installations.

This box held a telescope (REL33897.001) manufactured at the Commonwealth Solar Observatory (CSO) on Mount Stromlo, Canberra. A small observatory was established on Mount Stromlo in 1911, becoming the CSO in 1924. In July 1940, at the suggestion of the observatory's director Dr Richard Woolley, the observatory ceased almost all peacetime activities and devoted its resources to making optical munitions.

The Munitions Annexe made prisms and optical lenses, and all the grinding and polishing machines used were designed in the observatory and made either in its own workshop or in a workshop in Canberra. By the end of the war, the observatory ranked alongside the University of Melbourne as a centre for pioneering optical techniques and for disseminating them into industry.
