----------------------------Original message---------------------------- In 1985 we bought a very useful cart for our USGS archival map collection from Promaco Inc., 5685 No. Lincoln Ave., Chicago, IL 60659. It is described below: Mobile Service truck (cart), # V310187, 38-1/2" high, 24" wide, 42" long, 3 shelves, and with 5" non-marking casters. The shelves are zinc chromate plated wire with baked clear lacquer finish. We paid about $200 for this cart in 1985 but it has been used extensively and is still in perfect shape. Its also great for hauling large atlases. Betty Graziani USGS NMD Reference Collection, MS-522 Reston, VA 22092 e-mail: [log in to unmask]
