Right now there’s nothing specific to identify—your message sounds like a caption from a post, but I don’t have the actual image or the “comments” it refers to.
If you want a real answer, I need one of these:
- the image itself, or
- a description of what the object looks like, or
- the comments people are suggesting
Posts like “forgotten piece of history” are usually one of these common mysteries:
- old farming tools or industrial machine parts
- military equipment (shells, gear, aircraft parts)
- medical instruments from the 1800s–1900s
- household devices people no longer recognize (like old irons, crank tools, or telegraph parts)
But without seeing it, anything more would just be guessing.
Send the image or details and I’ll pin it down for you.
