Reread colorful days

I don't know what this lens is. Maybe this is one of unbranded Japanese products made in 60s-80s by lots of optical manufacturer like KINO or SUN. I explored to specify it in ancient websites, deeper dark weblogs and vast AMAZON forest but I surrendered. If you know about my Tele-Stratocolor 135/3.5, please tell me by leaving comments.
