The pics are much more in focus but a straight on shot of the are in question would be helpful. At the moment something doesn't look quite right to me for Akro.
They did make peewee corks but they are very uncommon. I would want to see better pics, for some reason these are very grainy, and I am not sure what's up with this . . .
Makes me think it might be a lookalike.
Multicolor Rainbo - bottom row, second from the right in your fist pic. Also, second from the left in the bottom row, and far right top row.
Also looks like a MK 3rd from the right, bottom row.
These are Multicolor Rainbos as opposed to Multicolor Swirls, which have a swirly pattern. Miller Swirls are National Line Rainbos (NLRs) and are a whole different beast. You can find many of the Peltier NLRs with a Miller Swirl pattern
