PA24 thanks for the pics and diagrams.
Interesting adaptation of a boxlock forging to a trigger plate form. It is the first trigger plate action I see with a full and removable bottom cover. Presumably machining was facilitated by access from below, and also cost less than a traditional boxlock with a split bottom cover. On the other hand the hollowed out bar is no stronger than a boxlock bar.
Puzzling that gunsmiths find less room to manouver and adjust trigger pulls in this action than in the usual boxlock. Makes you wonder how they are going about it.
