Ah cool thanks! Do you know what the cutout mates up with? I see in your screenshots that they’re all keyed various ways, I’m guessing they went into some kind of punch machine or something along those lines?

Edit: best I found is from here: https://patents.google.com/patent/US1859307

To facilitate the reassembly of the articles in customers groups, tag holders are provided, and to make confusion impossible, these holders are provided with characteristic admittance means, the tags having similar characteristic admittance means so that only-the tags of a certain number (and therefore of 'a certain customer) may be assembled on the holder having that number.

Makes it sound like there was a sort of rail that matched the cutout to mistake proof putting one person’s tagged clothes bags back together after they were laundered.

I did try a reverse search on Google, but it only gave me padlocks for some reason. Another poster found it though, thanks.

Yeah, it’s a little odd. On the desktop site, I can search “https://lemmy.ml/c/whatisthisthing” or “!whatisthisthing@lemmy.ml”, then I get no results, wait about 2 minutes, search again, and it’ll pop up so I can join it. On Jerboa, I can search and search and it never opens.

If a community is already on your instance though, I think you can open the sidebar and subscribe from there.

I didn’t realize there was one, thanks! I just figured out how to subscribe to external communities earlier today, so the link will get me there.
