Picked mine up in Brisbane. Are they individually numbered? I have number 32791 at bottom right on the back of the box.
Assuming you didn't make a typo, they might be individually numbered. My large box has 32691.
I have a list of all G1 characters that have been released in CHUG form. You can find it here. Please feel free to let me know if I got anything wrong so I can fix it.
