Hi. It has a polished pontil mark and unfortunately no etched marks that I can see. I thought it was worth a punt at it was relatively cheap and appears to be a quality piece. I admit that the Hoglund bowl is a very similar shape... Hard to know what to believe re Murrays work, some books say all his work is signed others not. I know his stuff was sold here in NZ. Does anyone know if Murrays pattern book is online or been published anywhere? Cheers
