Morning, friends!
Sharing the latest find - Verbesserte Rauch- und Schnupftabak- und Cigarren-Fabrikation. Leuchs, Johann Carl (Nurnberg, 1846).
It’s a German book on tobacco, snuff and cigars fabrication. Scanned book is available here: https://reader.digitale-sammlungen.de/resolve/display/bsb10305199.html

Many famous recipes there. Jump to page 200 for snuff.
