I don't remember ever seeing anyone talk about ringers not having fire, or having fire. Just that they're like Popeye with white and clear but only one other color.
Yes, ringer was a name on a box, presumably letting kids know it was for the ringer marble game. Yes, I think they contained more than one type of marble. I haven't ever seen any indication that Akro intentionally ran a line which matched our description of ringer. So the question is which marble line that Akro did resulted in the marbles we call ringers.
I posted that many people think it's the watery Moss Agates which are the ones people think of as ringers.
But Ann made me remember that Aces could fit the description people use for ringer, and might fit it better than Moss Agates do.
