Gemini 1/12th vintage car

[V12]

This is a Gemini 1/12th scale vintage car I got some time ago. The car was made in the UK and sold around 1980. There is not really much missing beside the radio plate but I struggle finding anything at Ebay or other sources. I would like restoring/completing this car as it´s very well designed and showing later at a rc museum website. So if someone also has Gemini cars or parts please let me know.
