They started with 1001; there were maybe 400 prototypes (pushbuttons) sold, many in Europe, while Ford took control of production. The latest one we know of is #1376 while the earliest registered is #1006. Incidently, the doorbuttons came from the Mangusta. Much of the trim on the first 50 or so cars is completely different than even the pre-L cars, so no matter what shape your suuff is in, hold onto it. Some had the battery behind the pass. seat next to the headers, cable release for the decklid and odd placements of accessories. There is a technical manual recently made available by PI, POCA and others that deals mostly with the pushbutton cars (Pantera Service Highlights, from Ford in '71) that would supplement whatever Pantera books you now own
