Older Mossberg adjustment screw thread locker ??

Does this look like a factory thread locker or added later. I've used some thead locking liquids but never seen this color.

That looks like high temp Threadmate VC-3. I do not think that would be factory.

I appreciate the response. Just a color I'm no familiar with. The rifle is in excellent condition and none of the screws appeared to have been turned, but with a 70+ year old rifle who knows.
