Nice box--Mega is getting old.
The big yellow one is called a "Bannana Swirl" imho and I agree that it looks like a slag (very nice, these may fool some CAC folks).
The big Angelo needs more images but from what I can tell, in what I have found in my archives, they tried to match some of the big ones with the smaller ones.
These boxes came with a bunch of different combos--yours is a nice one.
I found two of these on Ebay. One is marked differently--but the same thing.
Hmm I rechecked my post and one lists China? I love "WaveBreakers" those are Vacor.
