Hello Nick
I have an early Victor Special(Enduro) of 1966 which came back from USA in 1990 with 720 miles, so the bike was completely original and had E/transfer ignition which was awful, no advance/retard, these were fitted to the early ones, I would have thought that yours should have a battery/coil/points, but well worth looking at an electronic kit, tanks were always Yellow, far as I know. I get parts from Burton Bike bits. Lovely engine, great fun to ride and pretty looking bikes.
Good luck
John (Somerset)
