H&H put their single lock pin [screw] toward the rear of the lockplate and it runs from plate to plate. This makes the stock a bit easier to inlet as you can use the pin to draw the plates to their correct position; it also allows the detachable pin to have normal threads. Purdeys have a single pin near the top center of each lockplate that screw into the action, and the plate tails are sprung into position as the pins are tightened. A hand detachable Purdey type action must require ten times the labor of a Holland type.
