The underside of the driver's side tank, showing the transition between narrow rear splasher which only covers the reverser rod, and the wider front splasher (on the left), which also covers the vacuum pump. The joining plate was removed at the time of the photo. Photo: Tony Summerton.

The float mechanism which sits inside the fireman's side tank. It pivots on a hefty bracket, seen on the right, and operates a pushrod (centre) which locates in the gauge pedestal, seen in the background. The float itself is not yet attached. Photo: Tony Summerton.

Corrosion! This is the end of the lever to which the float is attached (replacement on the left). Photo: Tony Summerton.

A close-up of the above process, showing the rotor broach cutter which drills an annular ring round a central plug, and is a great deal quicker than drilling complete holes with a conventional drill bit. Photo: Tony Summerton.
