Here is my final opinion. The base is a later 1970 non notched or over the counter OEM base. The numbers appear to be hand stamped common with the early seventies GM. What the numbers mean is still open for discussion. The tool markings, seams and spot welds look OEM. The lid 100% is a reproduction due to the ramped outer edge. Anyone have any more to add to this I'm open to learn also?
