Alan,
Did you notice the grain spacing on the original top? Its reversed, compared to today's [standards] of placing the narrower grain lines in the center of the top. The original's top, pictured above, has the wider grain in the center.
I've seen this done on countless vintage martins and Gibsons yet players might freak out if its done that way today. Oh, how times have changed ... I bet that old OM sounds fantastic though.
