HP calculator prototype?

[Michael Eckstein]

I obtained this HP 8S caculator which design differs from the production version. Has anybody seen this design before? I suppose this should be a prototype of the HP 8S Non RPN calculator. The production version HP 8S was released mainly in the Asia or Australia market.
