Brass "E" Round Thing

[cambria09]

Hello All. I found this over the weekend at an 1880's home site. It is brass, 7/8-IN in diameter, with nothing on the back. Thanks for the view and HH. C9

There have been many inquiries about these, with no positive identification yet... But I'll cross my fingers that there is some new insight!

Here is a discussion we had a couple years ago...

Here we go again...

I beat my brains out researching this item on the earlier thread. Since so many of these have been found, I focused much of my research on maintenance for some common piece of home or farm equipment from the early 20th C - like a pry-off end of a grease tube or something like that. Note that many of these items have a pry mark on the edge. Obviously, I found nothing definitive. If anybody has a different angle of approach or any additional information, I'd like to hear it. Love to "put this one to bed" as the saying goes...
