here were pianos that could punch a roll, but they were rare - AFAIK there were one offs that the company who made rolls used. The better rolls labels "as played by [someone famous in 1920]" were played on such a system. Once in a while those rolls were used directly in a performance, but the most common use was an expert would use that as the master and then correct all the errors because the transcription system wasn't very accurate (I'm not sure in what way, only that the companies always had an editor make adjustments before selling those roll)

Some of them are on exhibit in a museum - but with a sign saying something like "this will never be restored because it exposes the user to poisonous mercury." If you want to know more join the Musical Box society (I'm a member), or one of the other international clubs for people who collect this type of thing (I know of several but since I'm not a member I can't remember the full name)
