Picked this knife up recently, and I guess I have deduced that it is supposed to be a Authentic German Trench Knife, similar to Gottlieb Hammesfahr Solingen-Foche knives I've seen threads about here, but it is not stamped as such. All that appears on the blade, or anywhere on the knife is "Kr. *picture of a skull* S." Wondering if anyone can tell me anything about it? Is it one of the Indian fakes I've been hearing about? I bought it because I was intrigued by the markings, and lack of markings on the knife.
