It was me that offered my ACE to Jay Leno’s Garage. I hope it happens and best-case IMO would be Jay and Pete Larsen, with Pete’s new mid-engine flat 6 ACE also featured.
I know there weren't too many of his original iteration floating around, and perhaps that is simply a matter of supply and demand.
It was Morgan that halted the supply of ACEs at 13 total, after they bought Pete’s designs. In his book Peter Dron mused why Morgan bought the ACE out, considering they carried so little forward; maybe it was an effort to learn a little and shepherd demand a lot.
