Raceface Real Seal headset concave odd gap. Good to go?

Re:

that's a fat rubber thing that sits between the very top metal compression cover and the top cover, protecting the compression ring thing from dirt etc.

not sure when it went, this real seal II design (quickly called real seal again) started 1994 they changed the design a bit in 2002 with a new compression setup, way after my time and knowledge.
Sometime between then?
