Original plumbing trade vintage catalog for THE LEADITE COMPANY, was located at 1400 South Penn Square, Philadelphia, PA. Manufacturers of Leadite, the pioneer self caulking jointing material for cast iron bell and spigot pipe. Used for making joints in water mains, shipped in powder form in sacks containing 100 pounds. Used by water works superintendents, contractors, mines, railroads and plants. Unbound from a large 1936 architectural catalog, this unique old three page technical brochure would display beautifully matted and framed. A fantastic addition to your retro plumbing collection. Pages are detached and contain a small amount of residual glue on edge.
