Oops!

One I'd forgotten.
I'd set my mind on another jug; there's an elephant of doubt as to whether I'll fill the month, which was my ambition, without checking at all.
I was sitting at the Disputer, decided to get the jug, turned and saw this up aloft beside the nag which pulled this, which has, incidentally, since been rebuilt.
I freely admit to knowing nothing other than it's "Older than me".
We used to have some Mam referred to as "Cranberry glass", I don't know if it "went" or "they" have it; I just know I haven't.
;¬)
Don't study it TOO closely, or you'll see the several places I've been "at it".
