I was trying to work out what the eighteenth month of 1792 was, then I realised it was American for 18th October. I'm amazed that the seal on that jar has held for over two hundred years.Ahhh the good old blend 1018, and from the year 1792? That's got some good age on it!
I'd figured that, but I decided to go with the more amusing answer.It's October 2018.?
