The revolver that my grandfather carried when he preached in a small church in Arkansas has a serial number, but I'm pretty sure he didn't fill out any paperwork for it.
It's pretty much the same as one you might own, but this one has stories to tell. ;)
“All the important encroachments to the 2nd amendment happened in 1934 and 1968. I don’t remember when the 4472 form started, but probably ‘68.”
I know for damn sure I have one that isn’t registered. It is circa Revolutionary/Civil war and uses black powder and ball. It’s a long, long, rifle and extremely heavy. Since powder and ball is sort of not modern ammo :o), I think that antique is safe.
So, you are saying, if one bought a modern type gun in 1934 and later, the govn. has the serial number of the gun? That doesn’t seem possible.
