Scale: 1:24. Plan showing part plans of the beams, and a section through 'Elizabeth' (1769) or (1807), a 74-gun Third Rate, two-decker, illustrating the use of iron knees for securing the beams and wooden knees.

It has been historically assumed that this plan refers to 'Elizabeth' (1769). However, the watermark dated 1796 would mean this plan refers to her at the end of her career because she was broken up in August 1798. It is more likely that this plan relates to the building of 'Elizabeth' (1807), which would date the plan to between 1805 and 1807.
