Thanks, how in the world did you figure that out?

Googling serial codes can get you somewhere.

Ok, I know this is a stupid question but which is the serial code and how do you spot it?

Right side, by your index finger.

Usually just look for anything that looks important or like it would be used for cataloguing and give it a go.
