I don't have any information on that, although the platters certainly
looked similar to those on the 1301, 1302 and 2302.

The 2880 was first announced for the S/360; the S/370 was not announced
until 1970, a year after the 360/85, and the original announcement did not
include the 370/168. I'd guess that your management simply did not want to
spend the money on a 2880.
