I never owned an original Phantom. I had a 1.5t for 16 years, but recently broke down and ordered a Phantom Mk ii. I exchanged e-mails with Bob Graham during the process. There is no Mk iii.
Here's what I learned: When original Phantom came out, Bob indicated that he continued to tweak things and over time this got to the point that enough had changed to warrant the Mk ii designation. A few posts mention these changes accurately.
After the Mk ii was officially released, Bob indicated he still continually tweaked things - it is in his nature. This included the bubble level, a screw tap to mount the bubble level and a few other "minor" tweaks he thought of along the way. Certainly nothing to warrant Mk iii.
I bought mine from a dealer that is heavy into analog and sells a bit of Graham - relatively speaking. He shipped my Phantom Mk ii back to Graham for an "upgrade" to include the last few "minor" tweaks, but they are very minor and it probably was a waste of shipping.
That's what I know.
