The patterns for this fancy trigger were made by John Bivins. Originally this trigger was designed to be pinned to the wood. The trigger plate served only as a "wear plate". We have added ears to serve as an integral pivot point. However, it is possible to drill the pivot hole high in the corner, and pin the trigger to the wood. Notice that the trigger is .077" thick, and the plate has a .079" slot. Assembled and pinned.
