Principles and practice of fur dressing and fur dyeing
A 1922 New York trade manual by William E. Austin, published by Van Nostrand, aimed at fur dressers and dyers and drawn from the University of California Libraries. The pictures show machinery used in fur processing: a mesh-sided rotating drum, a geared drum frame, a roller machine with a flat feed table, and a line drawing of gears and belts. A designer might take from them the mechanical precision of early industrial machine drawings, with their dense hatching, exposed gearing and plain grey-and-cream tones.
