No I mean Blue - Blue ribbons, w/ no shades of black. The only place I've seen a real good one is in Sami's book on pg. 145 in the aventurine section, blue ribbons loaded w/ blue av. I believe you have the book, take a peek @ 145.
Not mine, I think it was Ron's ??

I've always heard the same and seen many examples of both. Supposedly Akro bricks don't have the distinct 9 pattern like most MFC along w/ the lack of white in the base ?? Just what I've been told and seen, so mostly an opinion.
Not positive of the one on the (L) but the other 3 are Pelt Rainbos, the hole (blowhole) are unfortunately a common trait on Pelts. Which has me leaning Pelt on that one also. Can you get a pic of the seams on the one on the left ??
