Scoured the various guides and I can't find a match.
It's probably staring me straight in the face

The one on the left.
It has a flat, wide rivet and virtually identical Hong Kong COO (GMFGI is slightly lower, with more pronounced dots).
The 5 bar panel on his back is different. It has a curved top edge, as opposed to the 'normal' flat edge.
There also appears to be a factory error mold mark at the bottom of his neck.
