Need help identifying aftermarket UL pistons

Any of you know what piston brand has the mark EAA inside?
I know Superior pistons made in taiwan have a crescent moon mark. I'm trying to identify these standard bore UL pistons for a friend. He got this set in a parts lot. They look pretty much like Superior pistons but they seem a bit lighter and the wall in the skirt is thinner also. Let's see if i can attach some pictures.

Sorry, I couldn't attach the pictures the way I expected. Anyway, the first link shows the unknown brand with EAA marks and the second shows the Superior brand's crescent moon.
Any information will be very appreciated! Thanks in advance.

I've seen this mark before on eastern pistons. It looks the same cast quality as superior pistons, both from taiwan.
