It's part of the WW2 (and possibly earlier) Demolition Test Set. Basically it's a safety battery box that takes an 'S' (inert for long term storage) or 'X' cell as used in field telephones and the daylight signalling lamps. The 50 ohm series resistor limits the available current to less than that which will cause a detonator or squib to fire, and sealing the box means nobody can fiddle with it.
Used for testing firing circuits (demolition and also electrically fired artillery) safely.
What you have is the battery box that goes in the wooden case containing the rest of the equipment.

That one appears to be missing the piece you have, unless the army modified it to use the bare battery.
