This is a Small Micro Machine 1971 Plymouth Barracuda in Yellow with Red Flames.  It is made of plastic and is highly detailed, Note the markings.  This is about 1 1/4 inches long.  I bought this as part of a job lot and it is in good condition, but shows 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.
