Flush and recessed displays of hp 27s calculator.

Yes, the 27S as well as the 32S and 22S came in both flush and recessed bezel designs, same as the 42S. The recessed bezel came later in each case, though there's not enough samples of units with each type and S/N to know if they occurred at the same time; in all likelihood they probably did start at about the same time.

I have a 27S with recessed bezel, with S/N 3224S04180, and I definitely do find this display configuration/design to be easier to read than the original, flush style.
