Historical AttributesOn September 2, 1960, David P. Wheatland ordered a Wild research microscope, model M20 KGS along with a comprehensive assortment of accessories and nearly all the attachments offered. He told the Wild vendor that:
"It is intended to use all thse for comparison, demonstration, and some for investigation. Eventually perhaps other basic instruments may be ordered and the accessories distributed among them. We are anxious therefore to have the list as complete as possible to make all the tests and optical experiments."
DPW also ordered a complete set of brochures for the library.
The initial cost of the purchase was $6000.
