<Bodie State Park - General Store
There are a couple of rooms in the General Store and this one gets some light coming in through a window facing the street. I have no idea what the machine does. It was covered in old oil and, since it is a store, it could be used to sell oil for heating or running motors. One of these days I'll have to find out.
The right side of the room is a wall with glass panes that divides the space with the room next to it. That accounts for why the sun coming through the front window is lighting everything up as much as it is.
