PAM crown guard roller bearing?

[masont]

I was looking at a friends gen PAM Submersible and it has a roller bearing on the crown guard lever. When looking at the PAM website and in the window of an AD, it looks like some have and some don't have roller bearings.

I don't seem many reps with the roller bearing - does any one know which gen models should and shouldn't have a roller bearing on the crown guard lever?

If I am not mistaken the I series started the roller. I know that the Gen PAM 111 I and J that I have seen had them
