Hallmark help on copper and turquoise ring with a bell circled by lines stamp

It’s the old Bell trading post hallmark. The Bell Trading Post was built in 1946 and was in use as a Southwestern/Indian jewelry manufacturing business until 1974, that looks like one of the last styles they used. Not terribly valuable but a lot of collectors specialize in just items from there.
