Graham mount compatability.

I'd like to mount a Graham Robin on my Gyro SE, which has a Rega mount supplied with it. A Graham armboard for the 1.5 and 2.0 are available. Does anyone know if the Robin will fit either of these mounts. Unfortunately, the Graham offices are closed until the 28th while they introduce their new arm in Milan.
The Musical Surroundings website describes the Robin as compatible with the 2.1 and 2.2 armboards. The 2.0 should therefore also be compatible. The 1.5 arm had a sliding platform that allowed it to adjust to different armboards. This suggests that an armboard for the 1.5 might not necessarily be compatible. Good luck.
The Robin uses the same mounting hole pattern as the 1.5 and 2-series arms. Make sure that the bottom of the arm base to the top of the platter distance is sufficient to give you adequate VTA adjustment length, though, as I am not sure that is the case with the SE.
Thanks for the advice. I finally found a Robin this morning which is designed for my Rega armboard and is actually in the possession of a dealer. Hopefully this is the end of a month-long effort to get the tonearm. I hope the end result is worth it, because this analog upgrade has been a huge headache. Knowing what I know now, I would have gone with one of the complete 'tables from VPI or Music Hall.
