Howard Darrin's K-F dealership in Santa Monica was closed before Darrin production began. Edger Kaiser approved a bulk sale of remaining finished Darrin inventory to "Dutch" in late 1954; they were shipped to his custom car shop (the former dealership building, I believe, based on the pictures I've seen) and given Cadillac V-8 Engines and Hydra-Matics he bought from GM (or so the story I've heard goes). There is conflicting tribal knowledge that the batch also received an additional ID tag put on by the shop to show it was done by the designer so I don't know if such a tag was ever attached, let alone managed to stay with the cars over time.
