Hi Billy (Mike),
I've been trying to find some for a while now, and may have a lead or two. Are you looking for the ones that go on the Hummingbird frame? I would be happy to let you know if my inquiries pan out, and please let me know if you scare up a source.
The company is still in business in Osaka and appears to be using the some of the same graphics. You can find them at http://www.zunow.net. Nice pictures, but the text is a bit hard to follow.
