Silver hybrid bout Rustique info?

[rideon66]

Ok so I got this hybrid bout Rustique from Germany and it is a strange hybrid coticule. I have looked through hundreds and hundreds of images and pages looking for anything even close. I know some strange ones exist because I saw some in my looking. Only none with this silver to them. The edges have been incredible so far off this. A bit crisper and keener not as smart an edge as a usual coti. It will bite you, but leaves the face feeling very nice and refreshed with no irritation.

Anyway I was wondering if anyone else has seen one with this silver or has one? If you know what would make this color in a coticule? I can see layers on the side, with some possible LL coming through the center of this hybrid plus Manganese running all the way through showing on the bottom too.

First pics show the hone with a normal LL bout hybrid side next to it for color comparison.
