Hopicraft Eagle track mark

Can anyone help identify this mark? It has the hc and Eagle track but no ps. Could it still be by Philip or someone else?

Thanks in advance for any help!

I have looked and haven’t found anything. The Hopicrafts hallmark in Wright’s Hopi Silver is said to have been used until 1983. It was a shop owned by Wayne and Emory Sekaquaptewa, moved from Phoenix to Kykotsmovi. I come across a handful of pieces in my reference books that have this Hopicrafts mark along with the artist mark. Might do some research on Hopicrafts and its artist.
