   No it's a prototype. HP made clear models to test air flow (and heat
dissapation), parts clearance, etc. It's mentioned in the HP Journal
article for the HP 9845. I've had several clear HP calculators including a
clear HP-35, a clear ***RED DOT*** model HP-35 and a clear HP 92, and a
clear back for a HP-65 and I've seen a clear HP-41. I've only ever seen
them demo a clear unit ONCE, that was a HP-42 IIRC.

   FWIW I have a demo unit HP-85. The label on it says "demo Unit, Not for
Sale" and it has a 9999 date code.

   I don't think so. I've only heard or seen of ONE clear unit os any model
so AFIK HP only built one of each.
