Thanks Dan. I do have a concern that dates some new canning development was implemented in the US or England may not relate well to when a mutton canning operation in New Zealand got around to changing their methods. What would be useful, like in the case of the ointment pot, is a dated can from that period. Is Irvine and Stephenson , who owned the St George label, still in business, do they have records/sample cans that go back to that period?
