Few more relics, KG3, 65er and a mystery “L”

[pa-dirt_nc-sand]

managed to get out for a couple short hunts at some early sites I’ve crushed. Got to love that one great high tone in a really old site being a 1965 quarter… Any ideas on the “L” shaped piece. Found deep in woods in the middle of 1780-1850 stuff. Heavy cast brass with some iron remnants.
