PRSh reads this forum extremely rarely, I would assume. But what do I know? Maybe he skims through every night as he sips a scotch for amusement.
No idea on the materials for the purfling and rosette, but probably mostly plastic-based, but solid, not a decal.
EDIT: Oh, and why was this thread never moved to the acoustic guitars forum? Seems weird to be reading it here, even after so many years.
