According to this carb book, the 1975cc CF was only from 1969-70 (another book says 69-72 tho), and has a 361V carb, which also fits :
1600 Viva HC 1971-72
1600 Viva HC and Firenza 1970-71
1600 Viva and Victor 1969-70, and 1970 on
1600 Victor 34 series,
1760 Viva and Victor FE 1972-73
2000 Victor FD35 1967-69
They all have different carb ref numbers, but they also all use the same needle valve ( B17258 ), floats, gaskets etc.
Looks like the carb you have your eye on would be a perfect match
