Ah, you have one where the label gives the only FCC ID actually recorded at the FCC.
I do wonder whether Far East staff don't understand FCC IDs, and just alter the FCC ID on the label to match a revised model number (e.g. KB-6252EA → FMA44HKB
6252EA) without realising that you can't do that? I've seen a lot of keyboards with alleged FCC IDs that the FCC are not aware of. Either that, or the FCC are leaking records …
Also, mine has pad-printed keycaps. Not sure what they were up to, as I have an old Nan Tan board with pad-printing, so with yours they decided to give people a treat
