I don't think that have Myrick Vol III. I'll have to check it out. My parents gave me a copy of Vol 1 many years ago.
Below is a shot of Detroit Copper 2 which is located at Adobe Mountain Railroad Park in north Phoenix. Sorry about the poor quality! I used to drive by this one every day when I was going to school. It used to set along with another porter at the Arizona Museum near the capitol in Phoenix.
I have misplaced my shots of Coronado 2 at the moment. It is now at the Mining & Mineral Museum just down the street from the capitol.
