  No, they are regular EI cores.  Plain transformers used to supply control power for relays, etc. on MV busses.  Not high Z.  My HV wdg measures(DC) 6.8 ohms, LV 0.1 ohms with a Fluke 87. Here is my nameplate info but they will all be different.  They have pictures for most of them I think. 
  5kVA 60CPS 1 PH Type E17046
  H1-H2 2300V   X1-X7  280V  17.8A
  GE 193A6778 P38
  Electro Engineering Works    San Leandro, California
  I think mine is 40-50 years (no Zipcode) old but in good shape.  We have 4160V switchgear that old in service today.  This stuff is built to last.

    Are those suitable for ham amp use or do they have old style high impedance (and DC resistance) windings that are not that suitable for a big C only filter?

      I don't think this is what you are looking for but Monster Controls has used control power XFMRs.  I paid $950 for a 5kVA 240/2400V + Shipping. They only come in common medium voltage (MV) switchgear voltages 2400, 4160, 6900V.  Sizes range from 0.75kVA to 5kVA.

        have to have a C-Core.
