Hi all, I'm brand new to these forums because I'm not having a lot of luck digging up information, and I hoped I could turn to your expertise. I recently picked up a couple of Japanese racquets that I'm guessing are from the late 50's, were manufactured by now-defunct companies ...and that's all I know. One is a Futabaya Blue Volley and the other is a Kawasaki Streamline. Both look in very good condition and came with what I'm guessing are the original zippered cases. If I can figure out how to post photos of them, I will. Any information you can offer would help a lot. Thanks!
