Marconi 8318C supply unit - UK Vintage Radio Repair and Restoration Discussion Forum

Has anyone come across this 19" rack-mount PSU, please? It is a chunky unit that offers 150-250V DC at 200mA, stabilised with a 6080 pass valve, and 6.3V DC. Other valves are B9A and B7G. I can't find any reference - either to the unit or to the equipment it might supply - on Google. Ruggedised construction and tropicalised mains transformer and chokes, it might be military - but no military marks. Any information or clues appreciated.
