Rebel SL1 Body Designation: AA vs BA

[SharpShooter]

Greetings!  I just received my first DSLR, a Rebel SL1, and very excited to get into advanced photography!

Well, I actually received two SL1s, and since I only need one I will be returning the other one.  I noticed on the two boxes that one had a different body model number.

One body is listed as 8575B003[AA] and the other is 8575B0003[BA].  What's the difference?  Now I'm wondering if one is "B" stock or if the "BA" represents a revision change to the body.

Anyone have any insight?

Just different production runs.

Thanks, ebiggs1!

Canon customer support had separately confirmed the same answer.  They also added that, e.g., [BA] did not mean that manufacturing batch was necessarily manufactured later than [AA] just because the letters were in sequence.
