One of the most, if not Thee Most, mysterious of 2nd Lufts I have had the pleasure to examine. It has so many features that are unique to this rare maker.
Found this Hack-Werke recently, and thought I would post it here.

Note the interior of pommel is a very thin copper disk. I found that the feature is so when one tightens the pommel one finds that it aligns tightly and the pommel sits properly and eliminates the well known 'pommel spin' a known design challenge with 2nd Lufts.
The taper tang and grip fit is of extremely tight tolerances. There is no 'wiggle' even before the tightening of the pommel.
