We have a large metal ring on an eye hook.  It could be antique, unsure therefore listing as vintage.  The ring alone measures about 2 5/8" across the center - outside measurement.  The eye hook is about 3 3/4" in L with the hook portion being about 1 3/8" across the center.  A magnet will stick to this - not brass but does have some tarnish on it.

I will ship internationally, please contact me with your country for a shipping quote.
