Sorry Pat
Its really simple, its just the standard pathos trigger fitted at the rear of the gun, then a remote trigger mounted further forward with a push rod pivot pinned to it running inside a groove to the rear trigger. The push rod is kept from flopping out by a metal plate screwed into the wood leaving just enough clearance for it to slide freely, so as you pull the forward trigger the rear trigger is pushed by the push rod. I'll try and get hold of the camera again and get some pictures of that later on when the neighbors are back from church
