As development_cycle points out, that isn't a Kona seat tube. This may well be a 1993 Kona that has had a major repair, hence the respray, hence the non-standard brake cable stops.
If it's a Kona, the rear triangle is from 1993 as evidenced by the rack eyes being in the stay not above and by the triangular holes in the dropouts.
These two pictures are of 1992 and 93 Cinder Cones. As you can see, neither has a seat tube like yours, but the 93 has a similar rear triangle.
If it has a 1" head tube, that tends to suggest that it is either a Fire Mountain or a Hahanna.
