I need help with identifying a lens

I am a new Pentax SLR user, I was given a lens and can't decide what to do with it. Was wondering if someone could help me?

The lens is a Tamron 1:2.8 135mm No. 665324, if someone could tell me a bit more about this and whether I should keep it, sell it or what. The lens is in excellent condition, I have noted a pin on the bottom as well as a screw mount.
I am using a 200d

Put up a snapshot of the lens with all the lettering. It may or may not be a Pentax screw mount lens. Tamron, as a third party lens maker, makes lenses to fit many cameras, and even their own screw mount. The Pentax screw mount is M42x1 - a 42 mm diameter with a 1 mm thread pitch. The Tamron T-mount was, I think 42mm diameter, but the thread pitch was finer - 0.75 mm. Trying to mount the one on the other can ruin the mounts.
