I have never seen anything like that. Kind of looks like was not polished properly at the factory.

My guess is someone either rammed a bore brush through the barrel striking the backplate or had it chucked in a high speed drill

Just a SWAG but I'm wondering if the ejector rod turned out a bit and a novice thought the only way to get her open was to slim jim the center pin forward from the recoil plate.
I can't imagine that working. I can imagine a person trying before being educated or taking it to a gun store.

Looks like the cylinder isn't fitted correctly.
Looking at it closely two things come to mind, like ro #1 cleaning brush or other steel pointed object striking the pack plate. Other idea is someone over loading a ctg and the primer has been pierced and the resulting flame has melted or undercut the area of the back plate. Without holding it in my hand it's really hard for me to make a sound judgement.
Looks to me like someone stoned that area, maybe there was raised metal for some reason. I don't think it's a detriment, the recoil shield looks minty. Obviously the gun has had little use.
Certainly looks like user induced damage to me. I see some dents and scrapes. The dents could have been from a bore brush being pounded through the barrel or attached to a drill. The scrape marks may have been an attempt to remove some fouling by using a screwdriver or similar tool.
I doubt it was a bore brush or the gouges would have been around the hammer nose bushing. It could have been related to a binding of the cylinder by a backing out of the extractor rod. What does the star on the cylinder look like?
Looks like Bubba scraping with a hard tool or a stone, for what reason escapes me.
looks like the vertical scratches were an attempt to remove the raised metal from the damage done by ????....sure looks like bubba was at work here!
I agree with several above, somebody was scraping something off with a small pocket screwdriver. Perhaps trying to smooth down any raised metal from where those little dents are?
Now, reading again, Babysitr basically said the same thing.
I would imagine alcohol was somehow involved. Does the gun work?

It certainly appears to be intentional mechanical defacing of the surface. For what reason is anybody's guess.
Notice in the one picture the cylinder is off the yoke. Someone using a brush. slamming it in and out though yoke bore and moving it and yoke around while doing so. Or perhaps they thought peening on side of bolt tip hole would move cylinder over a bit during lock up. I have a hard time believing there is valid reason.Maybe a bur or something on ratchet did it during recoil, Any sign of anything on center of ratchet. Maybe a bit of grit got trapped there for a few rounds. If it would have been on the ratchet itself, I would think it would have circled completely as cylinder was fire in all positions.
None off the marks are anywhere near the firing pin or bushing. That area appears to be normal
If the rest of the gun looks good, it functions correctly I would touch it up and forget about it

Is it likely that some factory worker passed that gun on to shipping in that condition? Almost certain it would be a big NO!
Just to add to Steelslaver's comments and as others have said, brass bore brushes can have a steel wound center core that protrudes beyond the bore brush that most likely caused most of the damage over 60 years of misuse. Some are cut at the end making them sharp and potentially damaging. I can just see someone running the brush down the bore with lots of resistance until it reaches the chamber, then ramming home against the recoil shield. Over the years some dents may have raised the metal, which the owner then took a steel file and whittled them back flat. I would have a qualified machinist clean that area to match factory appearance and then touch up bluing to eliminate almost all the damage.

It looks like the hole for the bolt was made oblong by years of not fully depressing the thumb latch before swinging out the cylinder. In order to tighten it up they peened the area that was damaged until the bolt stopped moving laterally. Then rather crudely ground it flat.

Gary, there is no way that a bore brush can get down to that point while cleaning the barrel. That is the bolt hole not the hammer nose bushing. I tend to agree with those that think someone was trying to correct a problem with eccentricity of the bolt in the hole. It was rather crudely done.
You are absolutely right! I usually try stuff before I add comments, but did not think where the barrel lined up. No way a brush could damage the center pin area. Thanks!

Looks like it was caused by a human and not something via wear.
Some Bubba was probably trying to modify it to go full-auto.
Just a theory, mind you.
