I still have more sorting out to do. But in the meantime I tried again with the Gr�ner signature. With the large upper case �H� maybe, maybe not. With the lower case �L� - I think it probably is machine engraved. But at the low resolution of the images no certainty is attached.
In my sorting I did come across another image of the gold(en) appearing scabbard upper mouthpiece screw, Everyone has their own interpretation of tolerances. But from my own perspective it�s not a �minor hair� separation between the screw and the upper mount. It�s a fairly good sized gap. And I have no doubt it�s been removed (or at a minimum been backed out), and that it might have even damaged the screw slot in the process. Although to be fair, I can�t be completely certain of the screw being damaged from the angle the picture was taken. FP
