No telling who made, it chriscooper, but I'm sure it is good and early.

These very large carafes are not that common, (I don't have one, just 2 big turquoise ones, although I know a couple of folk who do have amethyst ones.)
Most do have a round polished scar.
Although Boffo stayed on until '77, I'm not sure polished round pontil marks continued after MH left - there is no evidence either way.
Perhaps it might be safer to assume they refer to as late as '77, when Boffo did leave?
Your base wasn't ground and polished because it simply didn't need to be.
It had already been flattened sufficiently on the marver.
The script looks later, which is odd, but perhaps that's simply because it had to be small to get inside the scar.
It's not Dobson's writing, or MH's; just an ordinary script. On a
very beautiful bit of glass.
