James, in case you didn't get my email, I have been able to identify your first mark,
as that of the Wallendorf Porcelain Factory of Thuringia, Germany. The mark has been in use since 1964. You can learn more about the company and its marks at Porcelain Marks & More, a site by one of the Project's members, C.S. Marshall, an expert on German porcelain marks.
I have posted a thread on eBay's PGP Discussion Board, asking folks there to help identify your two Asian marks, as shown here:
You can see the thread, post comments on it, and (hopefully) get the PGP members' help on these marks here.
You might also consult the Chinese marks shown at Gotheborg.com.
