It just took some 0000, a few small wire brushes and some time to get the majority of the rust off.
Bore cleaned up decent, rifling is visible but very faint. The twist rate is unknown but looks slower than the modern 1:16. It does about 2/3 of a twist in 18" just eyeballing it. Did not bother trying to measure it. Maybe it is some kind of black powder twist like 1:30?
The firing pin dings around the chamber mouth are pretty ugly but they do not prevent a 22LR round from chambering, action closes on it too.
I did not fire it, will let the owner do that if he chooses to.
After I got it looking decent I started looking for a box to return it in.
I was not going to put it back in the towel of doom.
All the boxes I had were too big or small. I searched the name of the gun again and found this image;
I had some wood scraps left over from a few recent projects and also a teen son being lazy on the couch playing video games.
My decision, "Bud, lets make a box!"
Keep in mind it is just scraps, did not have proper hinges, latch, dimensions or much else. Took about 90 minutes. I cut the pieces and fitted them and gave my son the assembly job, hot glue and finish nails.
It looked pretty ****** with a few boot prints on the wood and I did not have any stain or varnish so I did the ol' torch trick to "age" it a bit.
Also I included a couple accessories that I have had sitting on a shelf gathering dust.
They seemed to fit the look of the case and are not anything that would ever get near my Black Rifles
Threw in a couple boxes of 22 Short too, again, more stuff that just sits here.
Extractor knob goes in the hole, keeps the gun in position.
The white cloth has RIG on it so the owner can keep it protected.
Cleaned up pretty fair.
