The 62 is as close as you can get to a real historic Kephart without getting one from Mike McCarter (who had the opportunity to study the one Ethan Becker owns and reproduces it in every measurement). Becker and KaBar made the 62 as historically accurate as practical, but there are a couple of details different that would have added to the cost considerably.
That said, the 16 is the most practical of the Beckers in this size (although the 15 is a better fighter). A modern grip, modern sheath, and a Scandi type blade. The 16 is Becker's personal favorite.
I have both 16s and 62s, and a couple of McCarters, and I'd take either to the woods, but rather the 16 just because of the grip and sheath.
