Hi Steve ... That is helpful, but not conclusive? - Close up pics of a head (especially the cavity & sole) would help?
Anyway, if you look at the picture I have created below with your hosel on top, I am not convinced the writing
"Chromoly 4140M" is the same? - The etched numbers are more alike & both are clearly nothing to do with
the build date that is normally shown - What is clear from the photo is that the ferrule on your head is not
a factory fitted Mizuno one, as it clearly doesn't fit flush & smooth like the one in the 2nd pic? - The one in the
2nd pic is how I would expect them to arrive from Mizuno, but as per my first post, someone may have had
the shafts changed or bought a set of heads from somewhere?
A couple more questions:
Do all the heads have the same etched numbers on them?
What shafts & grips are fitted (Mizuno have their own version of the GP Tour Velvet & NDMC grips they usually fit?)
Was it a private sale or from a shop (Pro Shop or online)?
I still think Mizuno CS in the US is your best bet for the definitive answer ...Paul
