He may have meant it was the last one that AN had.
No need to get into a bragging match as to who has the last head.
That's easy. Don has the highest numbered head sold (number 248). I have the first production head (number 2) and the last, which is a 750 head, number 249. I may want to build a 750 one day. Or sell it when the price on the open market reaches $5000.
