Push-button switch plate 4-gang (Davisville)

I'm looking for a four-gang vintage push-button light switch cover plate. The picture shows a modern reproduction, but I'm looking for an old brass one that would've been typical in a Toronto house built from the early 1900s up to around 1950. Doesn't matter if it's painted, scratched, dinged, etc, but must be metal - not plastic or bakelite or the like, and must have the eight round holes as shown. Perhaps you have one sitting about somewhere that was replaced by a more modern one when the switches were updated?

Thanks - it will get good use!
