Hit the field again

[joad]

Was able to sneak out for another hour at my field. No coppers today, although did find some sort of emblem attached to a hunk of steel has the initials CS It looks quite old, maybe someone here can ID it for me. Also, part of a Tootsie Toy and a copper plate with french writing engraved on it. Thx.

Could that be a swing key-hole cover on whats left of an iron/steel lock?
