Here's my updated 3D CAD interpretation of the emitter/Mk-8 interconnector assembly:
[attachmentid=4894]
[attachmentid=4895]
[attachmentid=4896]
[attachmentid=4897]
And comparisons between Chris' sample and my model (please note that CAD perspective and photo perspective may not match 100% due to optic distortions in the photo and exaggerated perspective in the CAD, not to mention small differences in scale and geometrical dimensions):
[attachmentid=4898]
[attachmentid=4899]
[attachmentid=4901]
[attachmentid=4900]
I left a tiny gap between the ring with holes and the inner wall of the interconnector at the flange, because we know something was inserted between them to secure a tight fit. Either that, or the Dewert Mk 8 interconnector did away with the sealant material and was a press-fit between the two parts. Indeed, in Chris' front view, the seam is barely even visible - it's a hairline which separates the lighter gray ring from the darker gray flange... In the event the parts ARE assembled in a tight press-fit, I can eliminate the gap by either increasing the ring's OD or decreasing the interconnector's inner wall's ID. I also can't find any of the 8 side-drilled holes in the inner tube, as they appear in the cutaway diagram. Perhaps this feature too was also eliminated between the Mk 8 and Mk 9 or even earlier.
Chris, can you ask about those holes?
Upon viewing the model and Chris' sample side by side, I can already tell that the step behind the flange should have a larger OD and be just a tad longer. Once I have access to all the dimensions, I can just plug in the new numbers and the model should be dead-on.
I invite additional speculation and different interpretations - I just want to get this RIGHT.

P.S. Andres - the lips may indeed be flush in the screen-used emitter because the Ring of Holes was pushed further in than the sample Chris posted photos of. In my model, I only recessed the ring enough to show a step, but not enough for the lip to be flush. I'm sure my lip height is a bit off anyway, so it's premature to draw any hard conclusions.
