Rolling Block Help

[Hanz]

The owner of my local gun shop knows I like the older stuff and showed me this Remington Carbine and asked for help identifying it. He said it is chambered in 50-70 Government. Here are the photos I snapped.

They added some sort of HiViz light pipes to the rear sight (I think just epoxy):

After some time spent on Google I'm thinking this isn't original and was pieced together. I know it was completely refinished.

I'll continue in a following post.
