'80's Labatts Beer Bottle mold

Got this a few years back, hope I never drop it on my foot,weigh's a ton!
This came from a house I was working on, and likely used at Consumers Glass in Hamilton,Ont. I know it's modern,but how many of these have you seen? Unless you work at a glass bottle factory! And being solid brass,it makes a great book-end.Thanks for looking!
