I found another cool old bottle the other day. It's a Unigate milk bottle, and apparently the Unigate brand name was discontinued in 2000, so it has to be at least 18 years old. I'm thinking it's probably from the '80s or thereabouts, based on similar items I see elsewhere online.
I was walking Olga along the Black Path in West Hampstead, which I sometimes call the Trash Path because of the prodigious quantities of bottles, cans and other litter along its length. I was sort of absent-mindedly eyeing the trash as I walked when I saw embossed glass -- often a sign of something interesting. So I reached through the fence (the path runs along a fenced rail line) and pulled out this bottle.
Apparently Unigate was a big name among English dairies until the company was sold in 2000 and its name changed.
Anyway, I now have quite a little assortment of found bottles on our kitchen windowsill!
