Have you ever see this keyboard?? Weird AEKI... M0116C

[c.a.t.]

Just found a weird Apple Extended Keyboard I with a strange model number.

At first, it look like a regular AEKI with Alps SKCM Orange, but when you look at the label at the back, it says M0116C... But the M0116 is a totaly different keyboard.. And it's not a mismatch because it seams legit and the label also says Apple Extended Keyboard...

Anyone know about this model?

Thanks!
