There is a Focal-branded lens for which I wish to identify the manufacturer.

I have read that Focal is the Kmart house brand for optical equipment. They also appear to have encoded the manufacturer in the serial number, so in principle, I just need to find a list of applicable manufacturer codes. I have so-far been unable to find any relevant list.
