Scale: 1:48. Drawing showing the sheer lines with figurehead, the body plan, the longitudinal half breadth and the stern board for an unnamed 109 1/2 ft three-masted sailing ship. There is no evidence that this is the Neptune, launched at Buckler's Hard.

There is an unprovenanced pencil annotation: "Bucklers Hard / Lines of the Neptune / circa 1800", but the plan is plate 6 of a set published by Thomas Richardson of 26 Dock Street, Hull. The History, Directory & Gazetteer of the County of York for 1823 records a merchant and ship owner called Thomas Richardson living at 26 Dock Street. The printed plans in the collection from this set are: MSA0001 (Plate 1), MSA0002 (Plate 2), MSA0139 (Plate 2), MSA0003 (Plate 3), MSA0234 (Plate 3), MSA0004 (Plate 4), MSA0005 (Plate 5), MSA0006 (Plate 7), MSA0026 (plate 6) and MSA0027 (plate 6).
