detecting 1910s - '40s oilfield and houses. 

I love the axes because they are what developed the land on those homesteads. It was timber when they arrived, and with axe in hand, they cleared the land with ox and mule and axe to create farms on which they could live. I love military buttons because there is never no telling what battles those ww1 (or whatever war) soldiers fought in that war that button

Oklahoma has a lot of oilfields from the 1910s-40s
