Thanks to all. Here is pic of underside. Keeping the rifle and history together is a goal of 65yo me. Figure I'm good for next 20+ years, God Willing. Not sure about the next generation within our family though. I have made a pretty detailed biography of grandpa and grandma, both Marines in WWI through ancestry. If interested, I can send a copy. I appreciate the wealth of knowledge here and know I am starting about 50 years too late to reach a definitive answer.
