That's it!
It seems that the manufacturer's nameplate (C. S. Peets Mfg. Co, New York, NY) on the surviving car has led to its being exhibited as the "1908 Peets," but contemporary references to the make list it as the PMC. No one knows how many were made, but this car is "No. 33."
This is undoubtedly the most obscure make I've personally gotten to see "in the metal." I will post my own pic of it when I get the chance.
