I have been starting the twice a week and made sure to run the engine for good 15-30minutes ever since. Have some of the service history. Fitted a High quality ALI SPORT Radiator Pack with silicon hoses. Dash centre panel is missing BUT all switches are present. I did remove the Panel some time ago to repair the both centre vents on it, My mate took it and never saw it again as he has lost it.
I have also made an Video clip to described it better. Please feel free to ask.
