Found this at a house built in 1903. It's very light and I believe it is aluminum. It scratches easily so I've done as much cleaning as I feel comfortable with at the moment, but so far don't see any writing. Found WW1 tags with similar holes punched in them. Any ideas?
Sorry about the pics being sideways. Not sure why it's doing that.
