Ed,
 
We did an architectural survey of the former Lexington Army Depot in
Kentucky back in 1994.  The facility was built in 1941 as one of the first
bases for the storage, maintenance, repair, and shipment of ground radar
and vehicular equipment needed to transport radar.  The base later served
as a training facility for radar technicians.
 
The report citiation is:
 
Crampton, Alice, Julie Abell and Hal Sharp
1994    Architectural Survey and Evaluation, Lexington Army Depot, Bourbon
and Fayette Counties, Kentucky.  Prepared by Engineering-Science, Inc.,
Fairfax, VA for U.S. Army Corps of Engineers, Louisville District,
Kentucky.
 
You can also find the HAER forms for the base at the Library of Congress,
assuming they've made it in by now.
 
Good luck.
