The big batwing buckle below, is not broken, The tips are made that way, and I found a site that said one is in the Saratoga Museum? found at the Rev war site, and called it a "half frame buckle"
Some said it was a sash buckle for a decorative diagonal cloth belt across the chest, and others said it is a musket sling buckle. I did find a chipped broken brass piece of a musket buttplate shown here.
The other small batwing I don't know about either
Only two spoon parts found so far, one early pewter with backmarks, and one is silver plated brass with a name I can't see yet, nor know what era is was
and two smashed crotal bells...many things are smashed from yearly plowing/harrowing
