Johnny Lightning 1937 Cord 812 SC Convertible

Here is the 1937 Cord 812 SC Convertible from Forever 64 Release 7 (part #976). When cataloging my collection I try to note when the model was released and its part number. With Hot Wheels, this is easy; with Johnny Lightning, not so much. I found a listing of casting numbers for Johnny Lightning, but I can never be sure when the particular model was released.
