At some point in the car's past, when correct replacement brushes possibly weren't available, a previous owner probably fashioned brushes from what he deemed to be acceptable, available material, albeit incorrect for the application. It happened all the time with all sorts of things in the '50s. The 6 years of WW2 had left a strongly ingrained culture of "make-do and mend".
