... resend, original didn't reflect for whatever reason.

If you were looking at a Dahl plate transformer removed from a BC 
transmitter that had a center-tapped secondary, would you bet that the 
insulation would be good enough to use the transformer with a bridge 
instead of a full-wave rectifier, or would you assume that it isn't for 
safety's sake?

I have no idea of the age of the transformer. It has the standard Dahl 
gloss black paint with red data plate, and the terminals are mounted on 
pinkish-red terminal boards.
