I have acquired two pewter glass-bottomed tankards. The first is for the launch of the North Star 80/20 June 7, 1973. And the second is for the launch of the North Star 1000 Aug. 3, 1973. They are Birks pewter. Both have handles on the left. I got them in Charlotte County, New Brunswick, Canada. I have no information at all so anything you can tell me would be appreciated. Thank you.
I don't know anything more than what you see here already. However, you have alerted me to the fact that my general timeline for the company is slightly off, though the dates do fit.
It does seem odd that they would celebrate the building of the first of something since success was never quaranteed,, especially in a business of this type.
Both of these models did end up being relatively successful.
