Anyone know of this: 1396219 - the wikipedia page doesn't have this number.
The label on the back is so faded I can't make anything out apart from the signatures on the back, however I can see "6219" through the speaker grill with the date of sept 1988. I'm guess until I can get inside the first numbers are 139 (I kinda see part of the '9'). Also, the case appears to be a more yellowy color than a beige color, Would this be just dirt or actual sun damage?
