This series consists of a folder containing the quotations for particular components of HMAS Tobruk. Quotations cover mainly boiler, turbine, plates, pipes, and telegraph parts. Parts for both HMAS Tobruk and Anzac were often ordered and manufactured at Cockatoo Island Dockyard.

This series consists of miscellaneous files which relate to the construction of the HMAS Tobruk, but are not concerned with final cost estimates, correspondence, or drawings of the ship. HMAS Anzac, built at Williamstown Naval Dockyard in Victoria but whose main machinery was constructed at Cockatoo Island Dockyard, is often referred to in the files as ship/job number 186.

Drawings include welding specifications and instructions, body and framing plans, details of machinery seatings, bulkheads, plating, girders and gun supports.

This is a register to the drawings held in M2742. In the back of the book is information relating to Battle class destroyers, armaments, aluminium furniture, and a list of drawings received from the Director of Ordnance, Torpedoes and Mines in the RAN.

This series consists of correspondence with Williamstown Naval Dockyard in Victoria, the Naval Board, and others, relating to the ordering of parts and construction. In most cases, separate folders were maintained for inwards and outwards correspondence.
