Iron lid

[RustyRelic]

Found this in the campsite area. I can't get it any cleaner without doing electrolysis( I don't have that setup) but it's obviously an iron lid for a small box? The close up shot appears to me 1864 numbers. Anyone seen anything like this in their hunting ?

Could be a stove damper.
