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.
