Rebristled brush rolls and inserts for all makes and models used to be a staple of the industry. Rewound armatures were pretty much the same. Vac shop owners would send their worn brush rolls and inserts, as well as burnt out armatures, to the various parts wholesalers (many of whom are still serving our industry) and they would ship back rebristled brushes and inserts, and rewound armatures. This has died out as more disposable vacuums and components have come into use. I can also remember a time when the vac wholesalers carried a whole line of spray paints, particularly in all the Hoover colors, as well as hammertone and wrinkle finish paints. Things have sure changed.
