Anytime where you can find a brown K1 where the paint isn't turning back into the green base coat on the top of the tank/headlight bucket is a good thing. That color like some other Honda candies liked to fade away.
That's 'cuz the Browns (two of them) were either Red-over Green or Green over-Red. The Red-over-Green is the Briar Brown (sometimes misspelled 'Brier' Brown) and the other, like mine was, is Garnet Brown. The Garnet Brown was the 'metalflake' brown, as the Green topcaoat was the Valley Green Metallic, a rare (and beautiful) rendering.
My tank bag wore thru the green on mine by 1979, exposing the red. It was then that I began to discover how these brown bikes appeared. If you look closely at any of the brown ones, you will find a flaw somewhere, under the topcoat, that led to this "saving" of the parts by adding a different topcoat.
