Hi
I just posted this question in the shotgun section , but perhaps I should have asked here . New to me is a very nice condition Parker 12 guage . I am having a hard time unhinging the barrels from the receiver. This model has a screw slot in the hinge pin . Does this have to be removed to get barrels off ?

My other Trojan grade Parker barrels just unhinge once the forearm is off ,

What's up ? Thanks , Bob

The only thing I can come up with , is that the cocking hook is not disconnecting?

Got it --- held it the right way , and it fell apart ..dirty and very tight ..
