WW I Holster maker ID
 

Gentlemen, I hope someone can help with info on a WW I Luger holster. The stamping is on the rough leather inside the flap. I can make out Darmstadt and 1916 below it. I can't make out the maker Name above Darmstadt. Anyone know what it may be ? Does anyone have any tips on bringing out the stamping in this rough inside leather to be more readible. I plan to pick up Still's Imperial Luger book at the next gun show I make. Thanks, John
