The Kuribayashi 35mm reaches much deeper into UV, even a bit below 320nm and shows a rather high UV at 365nm transmission of over 80%. However the Kyoei Acall f3.5/180mm tele lens seems to be a very different beast, as it has no useful at all UV transmission!
I have written about that lens before HERE
Stay tuned, more will follow on that fascinating subject...
