Headset Recommendations for a 1990 Explosif - 1" ISO or JIS?

The cups turn freely and fall out.

Somewhere on Sheldon Brown 2 different diameters for the cups are given.

If not, what is the solution please?
 
Is it likely to be the case that the original Kona Control Centre components are worm - after all they are 25 years old or is there possibly another problem?

Hamster my comments on the Campagnolo Record Road headsets was based on the pictures on the Wiggle website rather than Ribble.

It's very strange, I had recalled seeing a retailer photo without the ports too. I went to the service doc in the end which clarified things. Maybe they did omit them last year; puzzling!
 
there have not been oil ports on these headsets for 2 or three years or at least as long as I have been selling them.
 
Re:

Is your explosif black with pink and blue splatter paint on it or purple,reason being i asked is if it's purple it's a 91 and 1"1/8th headtube,if it's the latter i might be able to help out. I've taking the XT headset out of my 90 explosif which fitted snug,i can take some measurements to give you an idea.
