Well the last one's that I can think of that run a 125cc was.In the low arch was the Cortina (Victacode V139)and Mayfair (Victacode V142) which was 1974.In the high arch was in fact the VC-125 Mark III (Victacode V138) also last produced in 1974.The last Utility was also 1974 (Victacode V145).
I think I see a pattern forming.As far as store brands sorry I really don't know as at that time there was way to many to remember.
So for Victa's main line I believe it was 1974 but with store brands I don't know I think they did go a bit later as I'm sure I have a 125cc engine that had a G4 carby on it.
