You could also look for a brake shop that does specialize in rebuilding classic car and motorcycle brakes.

There are not many places that work on drum brakes any more. The place I had used in Los Angeles is gone.
We used the shop below for a Libelle 201b brake, with fabulous results.
Be careful not to put it over on the nose afterwards!
Vintage get really busy. Best to book it and pay, then send the wheel when they're ready.
But its a bad time of year unless you have a spare wheel.
