This was found at an old mining site that was productive in the 1850's to 1910 range. Hoping to narrow down the year a bit and see if I can come up with the brand. Some of the name is visible, but, some letters may be missing or not what I think they are. What I see is: ?EIRCE & WO? Any ideas? Oh, there is still a square nail stuck in the metal at the top, so, that seems to fit the age, right?
