Here you go hoth -
First stage - http://theswca.com/lexicon/cromalin.html
The proofs are printed on sheets with other proofs - http://theswca.com/lexicon/proofsheet.html
And a common proof card is - http://theswca.com/lexicon/proofcard.html
A cromalin of any piece will exist in very little numbers compared to a proof, the cromalin was the piece used to finalise the card before printing began- if you want to have a read on cromalins I did a review of the Jabbas Dungeon one here - http://www.imperialgunneryforum.com/t1573-a-look-into-cromalins-jabbas-dungeon-playset
Thanks again for the comments on the Trilogos
