Has anyone cataloged who these markings' manufacturers belong to? I assume Circle T was Towa, and V for Vixen, etc., but other than that these are becomming collectable there doesn't seem to be much info out there.

Circle T is Kokusai Kohki in Japan who exports the University Optics ortho's.They also sell the widescan type III's.
I read in an old SAA post the owner of UO said the eyepieces were made at a factory called Tanny which makes more sense.Perhaps Kokusai Kohki bought them.
