Wasn't the SL drilled through, about a 6mm hole through the posts that the lower cradles pivot on? Also I think the cylindrical nuts had deeply countersunk faces, unlike these. Finally, the SL had a machined taper between the cylindrical part of the shaft and the upper, sandblasted looking part. though the guy who machined the grooves might have turned that taper off - it looks like there's some custom machining there.
From the AL lower cradles, I'd guess this to be a late-model NR, although the cradles could have been changed from the original.
I have no problem with the flutes going out the top - well, no practical problem anyway, I don't especially like the look, but it'll *never* break there. I do believe the flutes going down into the frame can cause problems though, on a bike that gets ridden - they channel grit down into an interface that's already fraught with problems. Be sure to take it out, clean it and grease it now and then. I sure hope the flutes don't go all the way out the bottom - that would be asking for bottom bracket bearing problems too. Again only on a rider though. A bike this beautiful will usually get pampered and only see a few sunny day miles. Got plans for it Wayne?
