Rafsob,
That is a very nice carbine. Congrats on the find. I have a friend that has an original Spencer carbine used by some yankee during the war. Unfortunately someone got the idea 40 years ago that it would make a nice lamp. So...they mounted it on a mill and bored the nicest, cleanest, professionally done hole through the left side of the action right into the chamber. It still makes me want to hurl when I think about it.
