HP 48SX with Strange Gold Logo

[JanS]

Ok, I did a USPTO Search for Mortar and Pestle logos and came up with this:

https://tmsearch.uspto.gov/bin/jumpto?f=...g6v.3.1154
(Record 1154 in the 19.13.01 - Mortars and pestles category)

So the Logo / Trademark Registration belonged to ICI AMERICAS INC. (incorporated December 3rd, 1986 (according to Bloomberg) and the registration expired November 4th, 1992.

Here's the english Wikipedia entry for the mother company, albeit a little thin on the american side of operations: https://en.wikipedia.org/wiki/Imperial_C...Industries

Another mystery solved!
But how many were made ???

Enjoy your rare 48!
