Beautiful guitar, David; please accept my condolances on the loss of your friend, my congratulations on acquiring such a sweet instrument, my extreme envy on the latter, and my welcome to the board.
I wondered about the '75/18 thing, but don't know nearly enough to comment on it - thanks, Michael. With all you know about vintage Alembics, you really should write a book, dude! I know I'd buy it.
Peter
