doglegleft,
Was it an oversight or was the fact that a rebore on an engine that old was not done correct? I, as a buyer, would not pay a premium price for an engine that was labled as a rebuilt that didn't include a rebore, align boring,new pistons and balancing in addition to the items you outlined. Also was the overhaul done by a Mercedes specialist? Surfacing the head and deck require knowledgeable adjustments to the valve train due to the overhead cam. Just making a comment so that you price it right.
