My grandfather was a First Class shade tree mechanic who loved Chevies. He had one much like this, which I think is a '51 model. He must have bought it in about 1955 when he gave me his '39 Chevy. Both were business coupes, which meant they had just a platform in back instead of a back seat.
I came across this one parked across the street from the Flying Star cafe at 8th and Silver in Albuquerque.
