✅ SOLVED Canteen stopper?

[WHADIFIND]

Hello folks! Just thought I'd post this here for opinions. In the "Today's Finds" forum it's been suggested that this is possibly a canteen cap. It has patent dates showing but I have no clue how to look it up because I don't know what to call this thing.

Here's the same pics I posted there. If another angle would help, just let me know.



As far as I can tell, it says, "PAT. NOV 24 1857 EXTENDED NOV 24 1875"
Non-magnetic.
Threaded
Textured edge.
The small circle at the bottom is still attached by a sliver of the threads.

HH!

Nice, I found one also and wondered the same

Due to the extremely fine-grain threading, I think it is the filler screw-cap for the oil lamp patented on November 24, 1857 -- US Patent #18,704. Check the original patent-diagram for the screw-cap marked part D. http://www.pat2pdf.org/patents/pat18704.pdf

I was thinking kerosine as well

Works for me. I was thinking this seemed to be too short to be a canteen stopper.

Thanks!

Seems right to me. Now, how do I go about patenting the coil in my avatar?
