"I have also seen, on disk drives, a B or a D in place of the second letter. Since all of my Japanese and Hong Kong built drives have 7 digit serial numbers (not a year + 6 digits like German production), I suspect that the second letter designates a particular source or factory within that country... maybe specifying a city?"
One of my 1551 drives (made in Japan) has a serial number "AD4 006xxx", so maybe that second letter, in this case "D", represents the market for which it was built?
My other 1551 (made in Germany) has a "DA4 xxxxx" serial number.
