Great finds Coin Head. The good thing I guess is you don't have far to go to hunt. Can't help on identity of items. Watch over your shoulder for the bulldozer.

Sounds like you neeed some help detecting all those sites...I'll be right over LOL. You are living in a MDers dream area. Those buttons sure look old, can't help with the identification, someone will know something about them.
Continued good luck at your next yard.
