Thanks for the reply, but I'm talking about changes between the 46 and the first series 47, not the Advance-Design 47. I'd guess there weren't any since production stopped just before the middle of the year. Maybe someone knows.
My Dad bought a new 47 in January even though he knew the AD was coming soon. His brothers thought he was crazy not to wait. Maybe he got a "deal" or something, I don't know.
