Tom, what you have is the original 426. They were hand made; every blade started life as a 110 blade stamped 426 and the clip point was removed BY HAND on a grinder. Tooling for the 426 drop point never existed. If you lay your 426 over a 110 you will see that it is possible, it just doesn't look that way at first. The "brown" handle you refer to I call "wine" or maroon.
The first set of 500 Alaska statehood etched blades used this blade in a 110 body. The second 500 (I think it was 500, maybe it was 1000) used the standard 110 blade; same scene with the Brown Bear. They all went to Cutlery World and most of the 426 drop points did too; the buyer, Dan Wright, was a drop point admirer. Dan still resides in Chattanooga and is virtually bedridden with multiple sclerosis.
I could go look up all this stuff but I'm going to guess and say it was 1983 and 1984
