Point taken Klaus, and thanks David, Brad.

I was looking into something else today and happened to notice a document that clarifies something above:

https://www.akg.com/on/demandware.static/-/Sites-masterCatalog_Harman/default/dwab2b98cc/pdfs/CMSE.pdf

So, correcting/amplifying a point above; E stands for XLR connector, 100% certainty. 

At some point after the initial C451, the AKG catalogs begin to list AKG C451C as well as C451E, in addition to CB, EB, and 452 variants. The catalog description states that C in this position (post numbering) is a DIN connection, E is XLR.

I may put all of the substantiation of the points mentioned earlier in the thread, in a dropbox folder or on imgur at some point.

edit: Oh, I now see the attachment field I failed to notice earlier. Many points were covered, Ill try to post some of the more relevant stuff in the near future. And it is nice to see even earlier examples David!

E = export = XLR
C = continental = Tuchel (back then)
L = Lemo for the RF (Austrian national broadcasting network)

which could be combined with:
B = bass control (low-cut switch)

so EB = microphone with XLR output and low-cut switch

452 = 451 with one resistor different, so that current draw at 48 Volts would be somewhat reduced (it was about 5.5 mA for the C 451, back when the DIN standard was still 2 mA maximum). However, as a result the 452 requires 48 Volt powering, whereas the 451 could accept 9 - 52 Volts. And even the 452 required ca. 3 mA. Back then, AKG and Schoeps' Colette system were like "outlaws" until the DIN standard was revised to allow a maximum of 10 mA/microphone at 48 Volts.
