This is a Small Micro Machine 1971 Plymouth Barracuda Police car in Black & White number 171. It is made of plastic and is highly detailed, Note the markings. It is about 1 1/4 inches long. I bought this as part of a job lot and it is in good condition, but shows a lot of play wear. The coin in the picture is a Dime to show just how small this item is.
I will gladly combine these small items to save on the shipping. Each additional Micro Machine item would be just $.25 for shipping.
