Four dots inside a circle is Ben Woollcombe

and the pot...

looks like it has been fired in an electric kiln maybe?

Such a cute mark that, surely made by pressing a button into the clay?

Oh yes, nice pot too! 

I was leafing through the Spring 1979 edition of the NZ Potter and found one of our mystery marks on p 21.
The four dots in two concentric circles is Ben Woollcombe who was associated with Dennis O'Conner and Helen Mason.

I can't find the original post for the pot with the mark that somebody wanted identified.

There is a link to the pot further down in the Quick Reply  -

I just looked at the article about him in the Potter magazine and think I was right in saying that the piece I have looks like it was fired in an electric kiln as the clay is dry and uninteresting. Now I would like to find one of his diesel fired or salt glazed pieces.

Thank you so much t&c as that is another mark not in the Potters Marks book

I think this is the same Ben Woollcombe:

He is still active but as a very talented painter.

Bought this trinket box today

Ferret said that the mark was too hard to get a photo.
