Platt, John, Lieutenant, Fl. 1780-1840.
The papers include a number of logbooks, orders and instructions, signals, watch/quarter/station bills, material relating to impressment, victuals and a number of sketch books and miscellaneous papers. Not all of the material belonged to John Platt, with one notebook being signed by a Charles Platt, 50th Regiment and other documents signed by a G.E Platt and an Edward Platt. The sea chest, inscribed "ROYAL SOVEREIGN", in which the papers were kept, was also donated to the Museum and is now with Weapons and Antiquities (see AAA3336).
