I saw this specimen of Gothic Light Face and I'd like try my hand at (re)constructing the lowercase, I'm aware that many of these early gothics didn't have a lowercase counterpart, however, looking at the Gothic Special it seems I could derive an understanding of how the lowercase might've been intended for the Light Face. My intention isn't strictly about revival – maybe a re-interpretation?

What other sources I could look at to understand how a lowercase could be constructed for this kind of gothic? (19th Century American gothic?.

Any help appreciated!
