Tim, I own Dave's NS-2 and it was an aftermarket addition. The Spector bridge is wider than the Kahler, and whoever did the installation added some wood (I believe it's rosewood) on each side to fill in the gaps. Both PJ and Stuart said it was a "tone sucker" when I told them about this bass, but I must say that it has a pretty solid sound.
I tried to add a picture of the bridge, but unfortunately I'm unable to do it from my phone. This is the only one I can upload, a shot of me playing the bass. If you look close at the upper side of the tremolo, you can somewhat see the gap. Gonna try and load up another shot in a little bit.
Oh, dude, that is sweet like a pretty stranger's reckless hands on the subway. Now I want it even more. I think my bridge won't have the same problem as yours: It's the smaller, import size.
Do you maybe have a sample of that bass' sound up on the web somewhere, in any kind of format? I'd really like to hear it. And it looks like you have a brass nut there. Mine does, too. Do you find that any use of the bar at all sends the bass out of tune, or can you get away with a little bit of wankery during a song, saving the dive bomb madness (which I'm SURE puts it out of tune) for the end of the song?



Must win lottery!
