Another interesting contemporary reference regarding Damascus barrel patterns:
Richard Mahrholdt, in his Handbuch für Waffenfreunde (Innsbruck, 1931), not only describes the manufacture of Damascus barrels but also illustrates several patterns: Banddamast (Ribbon Damascus), Hufnageldamast, Rosendamast, Bernarddamast and Laminettedamast.
He then lists the better grades as:
“Hufnagel-D., Rosen-D., Bernard-D., Crollé-D., Moiré- und Laminette-D.”
The particularly interesting part is what follows:
“Einfache Damastläufe wurden früher auch in Ferlach hergestellt, aber alle besseren kamen von Nessonvaux bei Lüttich.”
Translation:
“Simple Damascus barrels were formerly also made in Ferlach, but all the better ones came from Nessonvaux near Liège.”
So we now have Moiré, Hufnagel, Rose, Bernard, Crollé and Laminette Damascus explicitly documented together in a German-language firearms reference from 1931, with Nessonvaux identified as the source of the better-quality Damascus barrels.
Interestingly, Garibaldi Damascus is not mentioned by Mahrholdt, despite being clearly documented in the 1879 Liège Van der Straeten price list we found earlier. Perhaps Garibaldi was more of a Liège trade or commercial designation than a generally recognized pattern name by 1931 — but that remains only a hypothesis.
