Notes:

The given dimensions are for the box only; with the 1.8m cable assembly the weight is 1,128g.
The picture of its interior shows the relays and some capacitors presumably used to match the load impedance of the signals on the coaxial connectors. Although they are RF connectors the internal wiring is not consistent with RF signals not ones susceptible to noise.
This is part of the Dart Herald Fuel Flowmeter system and operates with a Fuel Indicator GP282/039 and GP282/040
