Here's three more for your list:

MOS 6567R56A  3982 ceramic KOREA     AM375716
MOS 6567R8    2584 plastic HONG KONG HH214105 
MOS 8564R5 CA 3786 plastic HONG KONG HH335852 3

Thes are from my spares.  


I noticed some questionable numbers on your list.

The 6567R5, by date and batch number on the bottom, would be in the middle
of the 6567R56A list.  This doesn't seem very likely.  It is more likely
that the 6A on the end was rubbed off or didn't print in the first place.

The 6569's with "NCAR 3" and "HO-30" on the bottom look out of place also.

The 8564R5's with "C", "CA" and "V" on them may be different ways of
designating the same thing.  At least, it looks like tha batch numbers
form a series, but it's hard to tell with only 3.
