Way back when I built this there weren't many police decals. I think these are Mount Prospect Police from the little Monogram 1/32 Malibu kit. The basic paint design was based on some photos I found of a CHP '41 Oldsmobile coupe. The red police light is a Monogram '32 Ford headlight. Found something similar in a photo of a '41 Plymouth cruiser from Long Island. This used to have an antenna, too, but that's been lost in a couple of moves. It's about 35 years old.
