The set looks complete. This is the MK 2 version that used only two valves (tubes). The MK 1 version used 4 valves so that's why there are two blank holes. The power supply was integral. Overall it looks in nice shape.
It needs the proper power cable and special dogbone for the T/R switch. Whilst it doesn't use a variometer there is a large varable Aerial Tuning Inductance #1 used in the system.
While the Canadian high power amp was being debugged the army began using this amplifier. It soon became adopted as the standard amplifier and the Canadian HP amp was never deployed.
It didn't have the same power output as the WS19HP (Can) but was considerably lighter and didn't suck the batteries dry.
