'64 Dart 270 Paint

Hey all, I've got my lovely 1964 Dart 270. The paint is largely in good condition, it's what I'd describe as maroon. I'm having a lot of trouble identifying it though, as it certainly seems period-correct, but not to be a standard paint from the manufacturer.

Here's where it gets weird- the rear exterior door handles were removed and painted over. The vinyl inside coordinates with the paint, and the sterring wheel (both original). I have found no evidence in the cracking or chips of a different color paint underneath, so I'm quite confused.

I suspect it might be "dark red iridescent" for the 880 from the time, but am not sure (source: 1964 Dodge Exterior Paint Chip Palette).

At some point the front passenger quarter panel was repainted, as was the trunk. The paint there has slightly more eggshelling, and is a little more brown of a paint. It has the same sparkle to it, but just a little less deep and red than the rest of the body work.

I'll add some pictures later!
