I've got an original used one off a '68 600, chrome is just OK. The last few NOS ones I got over the years weren't much better unfortunately....the chrome they used didn't take very well. Its got a cushionare/bolton grip since it was a 600 but they used the same throttle control from Japan.
$23 shipped if you want it. and will get you a current pic if you want to see better shots (these were it just sitting on the bike when I first got it and upside down), just send me you email to send them to.
