Original insulation trade vintage catalog for METALLO GASKET COMPANY, was located at 12 Bethany Street, New Brunswick, NJ. Manufacturers of Metallic Gaskets, Washers. Combination of deeply corrugated metal and long fiber asbestos cord that cannot be surpassed in tightness and resiliency. Disbound from a large 1931 industrial catalog, this unique old one page technical brochure would display wonderfully matted and framed. A marvelous addition to your retro industrial insulation library. Slight damp stain on outer edge.
