You can see pictures of a US VJ12 here:

Since you can see your power transformers better than I, don't yours look a bit heavier? If so, they probably are 50cps units.
By your tubes, you know your filament voltages.
Since your filament windings popped up at about half filament voltage, I'd say that the power transformers are for a line voltage somewhere near 240volts. You could gently power it up with the variac until the main filaments read 6.3 volts, with 5 volts on the rectifier filaments.
