The CK headsets are nice of course...9 times out of 10 a Tange Levin will do the job and look period correct as well.

Recently I bought one of the Token needle bearing headsets, but have not used it yet.

The high polish VO headset also looks the part, and works well on my Gilmour.

Ben's may have some of the black Paramount labeled Stronglights left as well...

Of course, you can never go wrong with Campy (other than $$$).
