Nuvo,
You raise an obvious but still very good question as it may both raise others and help answer some. Here (above) is another of Mance's often unique, and instructive photos.
Above photo's original purpose:
Here he has cut the top off a North-American (i.e.: swaged-top) strut to illustrate how one might preclude strut-tube bell-ringing with the always swaged down to 50mm at their tops (small bore) North-American struts and the requisite small O.D. B6/B8 Bilstein clappers, by positioning a short length of hose at the strut base preventing same. This belt and suspenders approach (to a known North-American and perhaps possibly the European situation sometimes?) guarantees things will stay quiet least till the gland nut loosens.
Also fairly visible is the dished strut-base detail common to everyone's struts and otherwise responsible for centering all smaller (for 50mm struts) dampers.
Together with the photo of the two damper bases above, one can see how the vented type damper base can't "block the drain-hole", while the non-vented type base might. If the water was above the non-vented damper base and outside the yellow tube, how does it exit? It may be that the route down & out (to the drain-hole mod) for any water in un-vented yellow-bodied Bilsteins is only via the thread's slim inherent interface clearances between the damper's screwed-in base, shaft and yellow tube? If such is the case, it serves to emphasize the importance of ensuring the gland nut seals are kept in excellent shape, something a carefully installed gland nut, boots and perhaps less well understood, even an OEM style top-mount (which lets the big chrome top tube rotate with steering inputs and the rest of the strut, which will preclude rotational seal wear) all help ensure.
Unable to upload photo to post at this time. Shrank and cropped the photo 10 x, still won't work!. OK, was able to upload a previously uploaded photo so, tried removing punctuation from file name of original target photo; and it worked!
OK, I'll try again (below) to upload Skull's (previously un-up-load-able without corrupting the normal photo presentation format at post #15 up thread) photo here which shows a European type 80 B4 front small OD (50 mm) strut tube-top being measured.
