Was hoping to use the F75 today but it's getting bogged down within the Postal Service. Went to the woods with my 505 instead, this is what I dug up, anyone know if the flat button is civil war, I think it is but not really sure, don't know what the handle went to either, the bottom side is flat, any ideas? Got the two ringer and round ball in the vicinity of the other two finds, not a bad day in the woods, only spent a few hours there
