No scale given, but possibly 1:48. A plan showing the upper deck of what may be the Queenborough (1748), a 24 gun Sixth rate. The dimensions match those of a Sixth Rate of the 1745 Establishment, and the plan is signed 'Earlsman Sparrow, 17th October 1746'. Of all the vessels built to this design, only the Queenborough was constructed and completed by Sparrow of Rotherhithe.
