Scale 1:96. A dyeline copy of a plan showing the outboard aft profile and plan view, illustrating the arcs of fire, elevation and depression limits and the aft 4.5 inch mounting for the Tribal class frigates Nubian (1960) and Tartar (1960). Each ship was referred to by a job number on the drawing. The plan initially included Eskimo (1961), but this was deleted by hand from the plan. This drawing bears a J. Samuel White builder's stamp dated 13 March 1963 and an Admiralty Overseer's stamp, dated 13 March 1963. This plan was also corrected up to February 1963.
