I am sure Brian knows this, this pin is not the hinge pin on a Parker, it secures the "roll" in the frame, the roll is the hinge pin. It is a feature in that the hinge pin was easy to change with an over size one. [/quote]

Of course. Just the use of terminology can be confusing. "Roll joint pin". Although most refer to it as a "hinge pin".
