Identification of hallmark on bolo

Hello- I inherited this bolo from my father. He bought it in the mid 1970’s in Arizona. The back is marked with a staggered “EH” with an inverted “V”(or tepee?) above the “H”. It also has a carved horse head on the front. The carvers name is electric penned on the back- Bessie Keedah. Who is “EH” and is he or she still around? Thanks. Dan

I looked in the hallmark book and do not find a matching hallmark. This is the boom and everyone was making jewelry.
