Went back to the old stomping ground. Tide was super low so I was able to strip it bear. Found three pieces of silver: The bar, the flat thin piece, and the elongated thing. Posted them in the What is it section. Somebody may know something. Hope you enjoy the picks...
Looks like you had fun at the low tide. I saw all your "what is it posts", sorry I can't help with any of them. Those zincs sure do get trashed at the beach.
