Coach,

All but one is vintage Michigan and the other an early Missoula knife. I was not part of the build back in the day but was aware the discussion. I was offered "in" but passed on the Missoula group which was roughly 10 or so knives which included Mosher sheaths with Zebra inlays.
Each knife was unique in its own way; no two were alike as I recall and confirmed as they now surface. My most recent group is not part of that build.
