Realistic Highball-2 dual impedance mic

[KK4RF]

Gentlemen,
     I recently found an old Realistic Highball-2 dual impedance microphone. I took it apart and found that it has a small audio-type transformer wired into it. If I wanted to use the mike at the high-impedance needed for an old tube AM rig, would I want to unhook the transformer and just run the cord directly to the 2 leads from the mike element? That would seem like the thing to do but I wondered if anybody there has used one of these mikes. Any help greatly appreciated.
