Any ideas on this one? Naval? Really pitted and flaking. The anchor is just a thin line. I think I see the arrows at the bottom. The top (from what I can make out) is a bit different. It's from an old site.
I'd never seen the V shaped stock on the anchor and so thin and plain. If it is what it looks like, then yeah I think it's pretty old. I found similar looking buttons on this site. Continental Navy! Possible?
