Hi Jack,
I guess I might have been 11 and the mower was purchased in 1973 opposed to 74, that probably makes more sense thinking back.
All I recall was that it was a spaceship compared to anything else in the street at the time.
Funny enough I still had it on the back of my ute when I picked up my son from High School and his first comment was that's a strange looking Victa Vac, mmmmmmm I thought, maybe he's sorta right due to it's appearance. Strange how a different generation looks at things different to what we do.
Cheers,
BB.
