Hi Jonathan,
in the original book kept in the Hamburg library, I made the photos published on both partner sites, a hand-written list of all plates is attached ... there you may read for this infantry plate:
80. Vom 13. 14. & 15. Reg. Linieninfanterie
Translation: "80. Of the 13th, 14th and 15th Regiment of Line Infantry
We had the same feeling about other troops shown by Suhr, that the artists have taken them from other sources available at this time.
All the best
Markus
