Ateliers de constructions électriques Vedovelli & Priestley : extrait du catalogue général.
A general catalogue of electrical equipment from the Paris workshop Vedovelli & Priestley, published in 1899 by the firm itself for electrical engineers and installers. Its numbered engravings show switchgear, resistance coils and panel fittings in precise line drawing, with cross-hatched metal grilles, bolted plates and wound coils rendered in fine parallel strokes that a designer could borrow for technical diagrams or industrial patterns.
