10 drawings are titled or annotated in a hand believed to be Lewin's (cf. copy of letter signed John Wm Lewin, filed at PXn 674). All but 3 of the remaining drawings are inscribed in sepia ink and/or pencil in a number of different hands. The majority have been annotated by Allan Cunningham (cf. Cunningham's hand, ML ref. A 1754 and MLDoc 252) in sepia ink, with some later revisions in pencil, and further corrections/verifications in pencil made and initialled by Joseph Maiden.

The majority of the drawings are inscribed with numbers in an unknown hand; 7 drawings (ff. a-e, 178a, 178b) are numbered in Library Officer's hand. 48 of the 257 drawings have watermarks.
