Hand Thrown Studio Pottery Small Lidded Container

Hello, I am trying to identify this maker's stamp on this small wheel thrown lidded jar. The closest I can find is a few artist's drawing the same symbol but no stamps. Derek Davis, Ralph Pardington and Ken Merrick write this symbol but none seem to mark with a stamp. I'm in New Mexico were Ralph Pardington and Ken Merrick had studios -what do others think? Thank yo for any insight.
