Ship Serial Numbers

[Ardrid]

I'm wondering where the other two ship serial numbers appear within the game's story. I've played through multiple times, with and without commentary enabled, and I have yet to come across anything. I've tried finding out information about the smuggling operation through different avenues and orders and still get nothing other than Erickson's/Adama's ship number. Am I missing something or are the other two codes an easter egg pulled from the credits or something crazy like that?

Where'd you find the other serial numbers?

In the 'Research Paper' Achievement Guide I guess. Maybe they're found zooming into other parts of the photo?

EDIT: Oh wow, this thread is from January.

So this is a MASSIVE necro, but I'm wondering about the numbers you have to look up for the Research Paper achiev as well.

One of them is a ship's serial number that you get from a photograph, but the other two? What are they?
