Unusual Marks like three half hexigons with numbers HELP?!

[MissAaron]

Okay, I have a plate, or charger. The markings themselves are not photographable. But I've included a photo of a drawing and a photo of the plate itself. It appears the markings are three top halfs of a hexagon. Under that are the numbers 105 in what looks like courier print. I THINK it's 105, Under that is sort of a line with down-turned ends and then three more numbers underneith. Those are all stamped numbers, Middle one is a two or a D. Below that at a slant in hand written or hand scratched numbers either K or R followed by 67. The stamped markings are less than a half inch in height, total.
