In 1956 he left Ashley Laminates to set up his own company called Falcon Shells. Peter continued to manufacture the Ashley 750 which had been renamed the Falcon MkI. About 150 of these Falcon-branded cars were made between 1957 and 1960 along with another Ashley derived car, the Falcon MkII. This was even more successful than the MkI with about 1000 being made over the same period.
Peter had the wanderlust in him and thanks to the success of the kit cars, he was able to leave his company in the care of others and headed overseas with his wife to live across the ditch in New Zealand. With all his knowledge of building fibreglass cars, Peter believed he would be able to set up a thriving business in this country and he intended to use his Falcon MkI and MkII bodies as a means to start it. Settling in Gisborne, he was seriously considering moving there permanently.
