Description:
A small rectangular, nickel plated brass box placed vertically on an insulator over a round metal base. The box has two small, round windows, one in the front and one in the back such that one can see through it. The brass box also has a thin brass sheet attached in the shape of a bracket such that its sides protrude from the sides of the box like fins.
The top of the box has a cap with two pipe connectors, one of them currently attached to an old, short rubber hose, and there is an opening directly on top of the cap.
The round base that holds the box also holds a simple vertical stand with a metal clamp that could hold a cylindrical object (a thermometer).
"H5" has been painted in white above the name plaque.
