MGB Corroded Heater Control Valve

With moaning, body contortions, scratched hands and fingers, much muttering about the designers and how did they manage to build them this way, I can say with some pride that the demisters now work and the windscreen clears quickly when the fan is switched on!

Operation of the various controls changes the air flow directions and even the fresh air vents have air flow direct from the vent outside of the windscreen as was intended.

Unfortunately the original heater control valve was badly corroded internally so I opted for a simple solution of installing a ball valve between the engine block and the heater and accept that I will have to go under the bonnet to adjust the simple new control valve.
