SU carbs with metal oil filler caps?

A nod of correctness to this conversation from Her Majesty and the Princess. "We ain't got no drain plugs"!

I was waiting for you to pop into this, Chris.

"Drain plugs? We don't need no stinking drain plugs!"

I'm going to have to go out to the shop and check on the metal caps for the dampers. I seem to recall plastic, but I do know of metal caps for this type of carburetor, whether SU or Hitachi. Old, old, old SUs had brass caps with knurled edges. I'm up to four sets of carbs now. I'll take a survey.
