I don't think our Vactioner wagon would have made that much smoke. Our HZ wagon wound up in a cloud of smoke like that one day in Castlemaine but it was for a different reason.
No idea, I know the HZ was never the same after we gave it a heart transplant with a 202, but we broke the top off number 3 piston and it kind of didn't run so we had to be towed from Castlemaine back to Dandenong (back in those days about 3-4 hours I suppose) by a Toyota Crown. The Vactioner was traded and never seen again but I have no doubt it's probably in a junk yard somewhere.
