Default ID This Device?

Can any anyone ID the (possibly military) gizmo in the attached photos? It is mostly brass with an ebonite or similar top and the base has four non-brass solid pins in a British B4 pattern, all drilled into the base. The insulated top has a single terminal and the base and top are riveted together.

The top is marked "X1141" and "958" is also scratched onto the top, possibly a serial number. The "anode" pin of the B4 is marked as "5" and finally the middle of the underside is drilled for a 4BA screw.

Plugging this into a B4 base would obviously short all the pins together, so a piece of test gear comes to mind. There is no electrical connection between the terminal and the base and pins, measuring on the highest range of my mulitmeter and there is no discernable meter "kick" which might mean there is a capacitor inside.

Any ideas?
