Hi Stu.
OK. That answers it. I don't know why I didn't notice that it was two pieces. Getting old I guess.
A closer look at mine also shows two pieces. but it is spliced in with a flat brass plate between the two pieces of wood, with two brass pins inserted from the top holding the two pieces together. Fortunately, the trigger and serpentine relationship work perfectly on mine. So I don't have to dis-assemble that area.
Thanks, Rick.
