Most accessories are catalogued under CHSI inventory numbers running from 1997-1-2062 to 1997-1-2223, and are stored separately. The microscope stand is 1997-1-0722 and the case is 1997-1-0723. All items are linked together in the Object Package "Wild M20."
The particular item does not appear on the original invoice and may have been added by David P. Whealtland.
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.
