[The Swed Hunther]

I did find thise the last time i was out, i have no idea what it is but it is looking old!
I have placed a coin next to it to try to estimate its size, the coin has the same size as an us 1cent.
Any ideas?

May be reflector far a candle or bullseye lantern if it was plated Just my first thought..
Is there any kind of attachments on back or anything to suggest how it was mounted?
