I have a turquoise and silver belt buckle. On the back is a letter K with a bent arrow next to it. I cannot find any info about this hallmark. Any ideas?

I just saw this hallmark. It said Kay Johnson -anglo. Found on internet under Hallmarks of the Southwest. Hope this helps.

P.S. I have a silver turquoise buckle with a crooked arrow hallmark but not the same as above.
