Scale: 1:24. Plan showing the section and plan of part of the magazine and ballast for Barham (1811), a 74-gun Third Rate, two-decker, which had been cut down to a 50-gun Fourth Rate Frigate in 1826 at Woolwich. She was then fitted for sea at Woolwich in 1831 for the Mediterranean. The plan seems to have also been used for America (1810) another 74-gun Third Rate, two-decker, while she was being cut down to a 50-gun Fourth Rate at Plymouth Dockyard between 1827 and 1835.
