I got a keg from a friend for a discount before I moved, and now that I am settled in and ready to brew, I am unable to open the darn thing.
I've read tutorials and seen youtube videos, and they all start with removing a retaining ring, but I can't seem to find one anywhere. The center "spear" part doesn't seem to move up or down either, and have used a wrench to depress the ball and degas the keg already.
Here is a picture if it helps at all. It was hard to see my phone screen in the sun, so if the picture doesn't help I can take some more for you.
Any ideas?? Help!!
