Northwest Coast carved silver Killer Whale or Orca Tie Clip

This is a tie clip Northwest Coast First Nations artist stylized carved Killer Whale or Orca. The piece is not signed but the clip has been applied and that may have covered up any signature or initials. Although it is not marked, I am sure the carving is done on sterling silver, but the clip is not. Size: 1 5/8” x 5/16” wide
