If so, are they with o-rings around the spoke nipples like the Alpina system, or are they taped ?

I ask because I have recently become interested in this since considering converting the wheels on my thumper to take tubeless tyres.

I agree with Gazza.
Roadracing bits can look "wrong" if the job is only partly done with a few bits here and there but when the whole thing comes together in a bike such as yours it looks very "right".
Lovely bike.
