Chrome button for Gotoh sealed tuners

[LARRY KLOSE]

A friend was given a Sigma (CF Martin) guitar.  Looks to be from 2002.  It's missing one of the chrome buttons from the sealed Gotoh tuners (full size).  Does anyone know where to get one of these.  Allparts and StewMac don't list them.

Thanks, 

Larry

Hello
If you could list a picture of this tuner, I might be able to hook you up. I have tons of tuning keys. Just a thought.
