Macintosh vs. 128K Revision

Most of us know that when the "Macintosh 512K" was released the original "Macintosh" was retroactively labeled "Macintosh 128K". The most oft attributed date for this transition is September 10, 1984 (the introduction of the 512K).

I've just come across an original "Macintosh" on eBay with the following manufacture info: original Macintosh 1984 (128k) was the 21172th Mac manufactured during the 41th week of 1984 in Fremont, California, USA.

Now, as there were 5 weeks each in November and December of 1984, that means this Mac was made sometime during the end of October. However, the case has the original "Macintosh" label, not the revised "Macintosh 128K" label. That means they were still manufacturing the original labels in some volume (21,172 in that week alone!) for 6-8 weeks after the 512K was announced. This conundrum suggests two questions:

1) If the 512K was actually announced in September, when did it actually start shipping (so that boxes would appear in stores and potentially cause confusion with the original)?

2) When did the "Macintosh 128K" labels first appear and did the revised 128K (512K hybrid) logicboard ship inside cases labeled simply "Macintosh" for a time (until it was determined the old label caused confusion)?

The third possibility is that someone switched the back on this Mac from a damaged original 128K to get more money for it (but nobody on eBay would do that). :b&w:
