Will try to shoot and post some pics later - but will share this for now.

I would like to add, though - that think about something. This pic where John is on the kit - no telling where it was shot or when or what circumstances, etc. Perhaps these were not Ringo's cymbals? Perhaps he did not have his with him and borrowed these from someone? A million reasons why it is possible that these HHs are not Ringo's. I don't know - just being devil's advocate. Saw the pic and had to make the observation.
Also - these Nickel-Silver MAC hats of mine - were identical in most every way - sold one to a close friend to use as a top. Then, also have a pair of the yellow ones (I think B8) - which are identical to these except the difference in metal composition. I use the yellow top with - of all things a Pearl CX-500 bottom. It seems to be the best sounding of all that I have - brightens it up and makes even more washy/wet.
