Object information

Physical description

A pair of inside calipers. The calipers, made of metal, feature two straight arms, which flare out at the ends, and are adjusted by a threaded compression nut on one side. The calipers are stamped with the maker's mark "B & S MFG CO. / PROV. RI U.S.A." and are engraved with the names "A. G. ROSS" and "R. Stanley / Adelaide".

Statement of significance

This timber and canvas toolbox and associated tools belonged to Alfred Ross who worked with the Government Ordnance Factory in Maribyrong from 1933 until his death in 1979. The Maribyrnong Defence Explosives factory complex which includes the Ordnance Factory has been placed on the Register of the National Estate.

The Neil, Lynette and Barry Ross collection makes an important contribution to the documentation of industrial Australia, particularly to the role of a federal government agency in the industrial development of Australia during wartime and peacetime.
