I would think that the best way to tell is measure the wire size of the 
secondary winding.  The second best way is measure he cross-sectional area 
of the transformer, as theoretically it is related to the power capabilities 
of the steel.... which you can back into current (after accounting for 
reasonable efficiencies).  180F seems a little warm for a CCS transformer... 
maybe Will can weigh in here...
