Remington Model 8 or 81. I have one. It was a premium rifle in its day. One of the first commercially successful semi-autos.
Yes! Beat me to the punch. I came back to add it’s an old painting called “Right of Way” by Richard Goodwin from an ad for the Model 8. At least according to the guys who posted it on the web a couple of weeks ago. I vaguely remember it from my childhood. I remember lusting for that rifle, felt I absolutely positively needed it, even tho I grew up in Kansas where we didn’t have grizzlies, or any kind of bears, or mountains.
