OP here again.
I've just posted a new thread that answers a lot of questions people have been asking. It includes Photos: both mine, and the ones the dealer sent to justify his denial of the return.

I don't know if the dealer might reconsider his decision. I do know all of us need to show a little good faith when it comes to trial periods and returns of these guitars we all love.
