I was given this knife by a friend, that he got from his brother's estate, his brother always claimed it was part of a set of knifes of Alaska, series of knifes thT were a very expensive brand of knife , his brother was a bit of a braggert and tended to exaggerate his knowledge of things , plus he was prone to getting taken advantage of by con-men on occasion, any I couldn't find any markings except this serial # , if that's what it is , thought I'd ask here before I made a fool of myself on some knife forum, I'm already known for one here so no harm done
