The original E/D P1 module may have been designated the 200; I'm subject to correction on that. The only physical difference among the Dress and Ladies' Pulsar modules (101-104) is the size of the digits; there is a very rare bar-segment display variation, but the module functions the same, and is not a separate model). There are digit-height variations among the P4 and Dress modules, but the smallest of them is still larger than the Ladies models; presumably, the displays were coming from different manufacturers (for example, the P3 modules come with two distinctly different LED displays, one by Litronix, the other from Monsanto). Finally, there is a very rare dot-segment display that is found on a few of the early Limited Edition (first 100) 18K Calculators. On the 4300, I have both Ladies' and Dress modules with the 4300 plaque on them, and without it. On those with it, there is a raised line that defines a "pocket" to allow the plaque to be mounted in a specific position; this feature is missing on the modules without the plaque, so, clearly, two different injection molds were used (green carriers seem to have been made only in the no-plaque version).
This doesn't seem to indicate any special effort by Time Computer to create some sort of color-coded identification system for the modules; rather, it looks just like random assembly of parts. The specific significance of the 4300 designation is open to speculation; all P4 modules seem to carry a similar plaque with the number "4000"...probably a reference to the 400-series of modules.
No doubt this post will be edited several times as new or updated information becomes available.
