NOS Chris King Nologo 3DV 2Nut (?) headset

Scored this bad boy today in a local junk merchant masquerading as a bike shop. It's a Chris King sans logos in a really vivid 3DV 'purple' (the pic really doesn't do it justice). Never been installed in a frame. The crown race looks like it might be Ti as well. The engraving on the lock nut says "King Sealed Bearing Oversize 1-1/8"

Questions:

1) Is it a 2Nut? I checked the Chris King website & the 'Grupnut' seems to have some funky retention system but this one seems pretty basic (i.e. a cone-nut & a lock nut)

2) Is it an old model? All the headsets on the King website these days sport the 'Chris King' logo. How long as it beensince Chris King offered the NoLogo headsets?

2) Does anyone know how much the Ti crown race weighs? Neither stainless or Ti are megnetic so weighing it is the only way I can think to tell???

Sorry about the crap pic. Took it with my phone in a dimly lit office...

Very nice find, been keeping my eye out for one of these myself.

Pretty sure this is a 2nut. Just installed one on a friends bike. Can we get an idea of how much you paid for it? I mean, did they know what they had there?
