"Emergency Tank and Vehicle Lamp"

[Bruce Parker (RIP)]

The 'charger' portion is attached to the vehicle in what looks like a standard household electrical box of the day. It has two switches on the front, apparently one to turn on the charger, and one the lamp(?). It also has a plate and stud which acts as a hanger for the lamp portion as well as being insulated to provide current. The cable attaches the lamp to the right box-like appliance that would appear to be a chargable battery. The lamp, cable and battery would be removeable and portable. This may be a stanadard UK AFV item or, being Canadian, could be some civilian thing impressed from local sources.
