These double set trigger parts are copied from a Vienna Jeager rifle, made available courtesy of Ron Scott. The plate dimensions are 4 1/2" long by 3/4" wide. Triggers extend 7/8" below the plate. This eight piece kit includes the plate, front and rear triggers, mainspring casting, a piece of annealed spring stock to make the front trigger spring out of, a screw to mount the springs to the plate as well as two pins to mount the triggers to the plate.
