Philadelphia Hardware and Malleable Iron Works
A trade catalogue of builders' hardware issued in 1878 by Carr, Crawley & Devlin of Philadelphia for architects, contractors, and hardware dealers. Wood-engraved plates show sash fasteners, hinges, latches, hooks, and screw plates drawn in three-quarter view with dense line shading and cast shadows, supplying isometric object studies, machined and cast-iron surface textures, and countersunk screw-hole details.
