No scale. An outline plan and section through a cannon thought to be from Dreadnought (1742), a 1733 Establishment 60-gun Fourth Rate, two-decker. The cannon was one of four guns on display outside No. 2 St James' Square, London which was owned by the Lords Falmouth (Boscawen family) between 1754 and 1923, when it was sold to the Canada Life Assurance Company. The guns were then transferred to the Tregothnan Estate, Truro, where they still exist. Four carriages were made at Portsmouth Dockyard at a cost of £36 each and dispatched to Truro. Edward Boscawen was captain of Dreadnought between June 1742 and about 1745.
