Speaker date code

[x66 714]

This is the original front speaker from my 1969 Norwood built Camaro. It doesn't follow the date code format that I've researched. An example of 466912 would indicate speaker 466, 1969, 12th week. My August of 1969 doesn't follow most of the known rules anyways. Can anybody say why this is different? I'm pretty sure that the date code is April 24th, 1969. Thank you, Joe

Your decode of date seems correct. I have seen that format before. I don't know if there was more than one supplier.
