lens quiz - green letters, and one red

[btgc]

Hello,
please help identify lens manufacturer - it's been told to be K-mount tele-something, on nameplate (front not barrel) there's something written in green letters and next to this stands red symbol (or dot) ? What this lens is about ? I googled quickly, though couldn't find even manufacturer. Hope evil SLR users will tell manufacturer or any-good in eyesight :)

Was there a picture meant to be attached to the original post ?!

seems that it is tokina zoom lens, something like http://i23.ebayimg.com/01/i/000/7c/1b/bf3d_1_b.JPG, hard to tell more specific.

Even before seeing your last post, my guess would have been one of the better Tokina lenses.

Well, initially I already set on so called off-brands, it just took time to sort out that it's exactly Tokina, which is referred as value for money.

It looks oddly, though, like there isn't front element, though I've found other pics where depending on light ang angle one can clearly see beside front element.
