James,
All pre-war televisions, electrostatic and electromagnetic, except the German E1 used brute force HV developed right from the mains. Only the E1 used a flyback. There is no issue with changing the horizontal frequency on any of these pre-war sets. I have run my 12" electromagnetic RR359 from 240 through 819 lines with no changes to the circuitry, just adjusting the coarse horizontal control.
