I dug mine out. I haven't handled it in a while. The Gau marking is "Ns." The fit of the grip to the lower guard is near perfect, except for a small gap on one side. The lower guard fits the the throat perfectly, as far as the contour goes. The blade shoulders perfectly fit the lower guard. Not a hint of a gap when held up to the light. Additionally, the age toning of both guards appears to be identical. Unless you want to question the Gau mark in general terms, this dagger is perfectly "normal."
