Wait, stop.
I was not referring to a "lid" as in cover, I just meant the little trap door at the upper left for the DIP switches.
Also, the trap door is not an indicator for the switch type, but I think that the earliest ones did not have it, and might be blues, while the later ones did, and were all or mostly whites.
Somebody that knows, like didjamatic, should weigh in here. I have had them with and without the trap doors, and all of mine were white.
