I recently came across these citations which likely have useful material for cribbing for scroll texts. Since I don't have time to track them down yet, and others may also find them interesting, I'm posting them here:
- A Collection of Miscellaneous Grants, Crests, Confirmations, Augmentations, and Exemplifications of Arms, part 2, ed. W. A. Littledale, Hrl. Soc. 77 (1926). (and probably also part 1!)
- J. Nicholl, Some Account of the Worshipful Company of Ironmongers (1851), which includes the text of their grant.
- The Annals of the Barber-Surgeons of London, ed. S. Young (1890), which also includes the text of their grant.
