Found this for example. Plugs like the ones presently used on tubeless tires. This also shows the tape as mentioned on the tin's instructions

Thank you for posting that. I’d actually found that article and have a screenshot of it. I also have a Wald rubber band tool, new in the box.
Mine is from 1923.
An interesting observation is that the Scientific American article is from 1896 and is about bicycle tire repair. If you think about it, bicycles once occupied the kind of space something like artificial intelligence does today.
