Mannlicher Mauser markings question

[DavidJayUden]

Cheekpiece is definitely an orig. part of the wood stock.
Reading that signature on the magazine floorplate is no easy task, it being in a scroll, flowing, script and having characters I don't understand. Not to mention that some monkey buffed it and partially erased some parts of the letters. There seems to be 2 words in the top line and one on the bottom, something like Gilrurd Simimund, Braunschneig (or ncig). Maybe GILRUDER SIMINRIND, BRAUNSCHWEIG.
I just don't know.
