I used to live over the hill from that mine and its mining town, known both as Lawrence and Hill's Station, which is likely where this picture was taken. The mine ran under my house is a leafy Pittsburgh suburb, and operated until it was flooded by a breakthrough from the adjacent, closed Montour #10. The rail line that swung like an arc south of Pittsburgh connecting the Pittsburgh Consolidation Coal Company's mines is now a popular rail trail.

Teaching a cat to use a shotgun can lead to nothing but trouble.

As subsailor says it's probably a Remington shotgun, a "lifter" design like the Remington-Whitmore. It looks like cleaning and oiling time (which I'm not sure I'd do in such nice clothes)

of 1600's Dutch painting.

Like fanhead, I'm all about that fabulous chair. What a work of art. The kitty ain't bad either but I prefer tuxedo cats.

I would trade the shotgun for that gorgeous chair. And I'll throw in the cat.

Looks like a very old E. Remington & Sons 12 Gauge.

When the cat, Mary Ann, currently sleeping at my side was younger, she and her sister would accompany me when I would go out on our property deer hunting. One evening, I was sitting on a log and noticed the cat sitting in front of me was staring and her ears were pointed. I raised my rifle and spotted a buck about 40 yards away. At the shot, the deer ran and Mary Ann ran after it. It went into a thicket of briars and I had to work my way in. When I got there, Mary Ann was sitting on the deer's neck, swatting and biting its ears. As good a tracker as she was, I was never able to train her to retrieve.
