Mac sanyo dynamotor code stamp

Hi all, I have a sanyo dynamotor geared hub. It was given to me a while back and set aside in the workshop for future use. I dragged it out today and had a look. It has a code stamped on it - MAC074933. I have tried googling the numbers however nothing comes up.

Does anyone know what these numbers mean?

I dont have pics atm but will snap fo tomorrow.
Thanks.
Matt.
