You can probably identify the lever screw and its keeper at the lower front of the receiver, it's fairly obvious. The action is fitted with 2 internal plates, one on each side, each retained by two screws and a locating pin arranged in a slanted fashion on the action's sides and encompassing the entire action side(s) internally from top to bottom. These internal plates contain cocking cams for the striker. There are 2 additional small transverse pins visible, one for the trigger and the other at the extreme rear is for the internal safety lever.

As the finger lever is lowered, the block moves downward and the internal cocking cams withdraw the striker rearward into the cocked position, ready for the next shot. The proper timing of this striker withdrawal is critical in order to prevent the striker nose from hanging up in a fired primer when the block is already beginning to move downward. This timing is IMO the single biggest downfall of many earlier single shot smiths, they simply didn't understand that the cam plates should be specially timed to act as mechanical striker retractors.

Several of the pictured actions also have a second small pin for the additional DST trigger and also a larger takedown pin located transversely through the bottom of the barrel's thread shank.
