Here is a detailed pic of my lens:

It is a Spiratone Sharpshooter 400mm f6.3 that fits a Canon FD camera body. But, I can unscrew the end piece of the lens near the mount where there seems to be a shiny insert seen in my left hand that has 3 set screws holding it in. Is this a T mount lens with an FD adapter attached? Anyone know how I can get this to mount correctly on my K30? If it's just a T mount to K mount adapter that I need I would order one but I'm not sure what's going on here. Any help appreciated!
