Nan had a badge engineered Pace with the Victa Monaro style hi arch base, also used as the store brand hi arch alloy base. It would have dated anywhere from the late 1970s. Clue: had the G4 carby with grey float cover without primer, facing outward with snorkel on the right hand side.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
