Source for Lionel Pre-War 158 Motor Brush Holders

[NNJRailfan]

I recently acquired an early 1920's Lionel 158 cab.  I need to replace one of the motor brush holders, which is basically a strip of copper with a "cup" at the end to hold the motor brush. I searched Olsens, but no luck.  Anyone know of another source or pre-war parts where I might find it?
