Is this the mark of Gary Hebley?

The Ferret thinks this is Gary Hebley's mark, but as we already have two different marks for Gary, I would like this one confirmed please, as this is nothing like the others.

Just wondered if these are one in the same person. My art teacher at school in Napier was Gary Hebley and I remember he very into potting.

Oh goodness me Truffles thank you so much for pointing this spelling out.
The Potters' Marks book said he came from Hawkes Bay and they have three marks for him in the book. None are like this one however, so I don't think it is his mark or work.
We already have two of his marks in the Marks Gallery.

Phew
