Graham Phantom II 12" - dimensions and overhang

Hello guys,

I come from Europe and recently purchased Graham Phantom II tonearm with 12" armwand.I was missing specs for 12" armwand (in manual are specs for 9" and 10"),so I emailed to Bob Graham and asked him for specs for 12" version. The answer was,that 12" version should be adjusted same as SME V 12". Bob sent me document with SME dimensions as well.

So regarding this document specs are Leff 308,8, overhang 13,2, mounting distance ( Pivot-Spindle) 295,6.
To adjust mounting distance is easy using any quality protractor. I used Acoustic Solid.

So with mounting distance adjusted to 295,6,here comes the thing.
I should set overhang to 13,2 regarding to specs for SME V 12",but simply

Has anyone figured out what's going on with the 12" Graham?

I have one and using the SME 312 mount template the tonearm base angle does not allow the arm to swing all the way to the run out of the LP.

I'm going to check on this again soon but if anyone has more data it would be great.
