Dear Norris, I am rather surprised that no one else responded to the Hetchins fork enquiry. They were not unlike the Dunnelt or Dayton type quirky forks, thanks for supplying the correct name. If my memory serves me correctly they made a big sales push on these and you could specify them as an extra. I hadn't realised they were so rare until you relayed the Alf Hetchin conversation. The only thing I thought I was being April fooled on was the "Pork pie reference" which is called Traif or Treyf in the East End, not kosher. Once again many thanks for your knowledgeable input on the subject. Yours fraternally Frank.
