HP54C ?

[Allen]

I stand by my hypothesis from this discussion:

Quote:The closer the seller lived to Corvallis, OR, the more likely an unusual item is legitimately rare/original.

Given the labels match the original HP27S exactly, and the provenance is from the HP factory AND the serial number 2743A-00049 puts the calculator in the same week as the earliest known model, I suspect this is probably an early 27S that was uniquely marked to keep it from being sold as a regular production model later on.

Also interesting that 27*2 = 54 but that could be coincidence?

Sad "the light does not work"
