Well, here is a clear picture of the markings, (assuming I uploaded it correctly to the website.) After re-examining the stampings with a stronger magnifier, I saw that the responses from the forum were exactly correct. I misread the first stamping as a "K", when it was really a partially stamped "R" Thanks for the help!
