Klaus, I wonder if the Teflon CK12 in the C414 ULS and the Teflon CK12 in the TLII are "different" capsules.

Off topic or not, it's an important distinction that readers need to know:
These are two different Teflon capsules. The original CK12 Teflon was rather gray in sound, and neutral in its midrange response.
In the late 1980s, AKG tried to regain market share for the 414 series of solid state mics by re-shaping the backplate of that capsule, using (should I be proud?) a couple of my fine tuned original CK12 brass capsules from Peter Wolf's (Austrian producer for Foreigner, and others) C12 collection as template. They then added the"TLII" suffix to the otherwise unchanged 414 ULS.. They also used that same capsule in the re-vamped "The Tube" mic, which was consequently renamed "C12 VR".
So, quite different from, let's say, Shure, which used the unavoidable capsule manufacturing tolerances to segregate SM56, 57, and 58 capsules, there where actual design differences between the two CK12 Teflon capsules.
Why you would experience such a large spread in high frequency response among otherwise identical designs, I cannot understand, as tolerances for capsules (and whole mics) are normally limited to a max of
