Here's the one I purchased last year at Marti autoworks.
when looking closer to the pictures that Jeff posted it seems that the initials 'RS-12' and '#3' must been placed vice verse (for the first picture)
but are placed correctly regarding to picture 5, with a slight detail that the initial 'RS-12' should be rotated 180°.
Just an observation, not knowing at all if it makes any difference for judging
Kind regards,
Jeroen
