Joe's reference knife on E-bay (see bad pictures above) is first year, maybe first six months. Key is what looks to be the 1/8-in leather spacers (pictures are bad, need close ups)... those were superseded by thinner leather, then fiber pretty quickly. This is backed up by the appearance of the flutes on the collar and cap and some other features. I posted my opinion on the progression of spacers etc. on early bowies and toothys in the dating a bowie line. These all are nice.
Sam, anytime Auburn beats Alabama it is luck.
