The second one looks similar to one I recently picked
up at a hamfest:

It had the following marking:

and probing and testing revealed the following:

I recently posted the following on this transformer:

With the capacitors shorted out (the way I got it),
and placing 10 vac across each cap, using various
combinations of taps, I get (assuming the 10 vac is
really 120 vac) 120, 240, 2,160, 2,280, 2,400, 4,320,
4,440, 4,560, 4,680, and 4,800 out. If the "primaries"
can take 240, I get double that. This arrangement also
assumes that all of the windings on the "output" side
of the transformer can take 4,800 vac.

Good luck.
