Here's a nice and complete Model 89. Complete other than this one doesn't have the power nozzle which could be that the original purchaser didn't go for it.
Per Dougs website it's 1967-1973. You might want to have a look at his site as he has a lot of Canadian models and US models on every make here's the link
Thanks Pete. I'd make the run to Blaine if it had the original hose! That deco splendor ZB30 is the one we had when I was a kid, it was a thing of beauty.
