Yes, I have checked them, and replied to you. Do you really want to continue this debate after already being told you're wrong about sliding extractors being late, and rotary being early? What would it do for you for me to point out another error in your PM pictures, other than it showing a lower screw for a tension spring used for rimless cartridges on a late model Rolling Block? You admitted you don't know Rolling Blocks, yet want to continue this debate.
The OP's gun doesn't have this screw, so it's irrelevant to determining the period of his Roller. His is a late model smokeless action, built for a rimmed cartridge, or reworked to a rimmed cartridge chambering.
I think I'm done with this discussion, and wont respond to further posts with you.
