Were Singapore made HP-32Sii produced with different keycaps?

Given the process described I wonder if what we are seeing is that the outside final mold was used for all calculators using the same keyboard shape and the immense pressures they described slightly imprinted the most common keyboard done with the mold into the mold after long use leaving a light outline in the shape of commands of say a 12c keys on a 15c keys.

P.S. Great article but the image isn't a 48SX given the equals sign at the bottom.
