[Healeys] tri-carb choke cable - knob

[jmsdarch at sbcglobal.net (john spaur)]

I have had two 1962 tri-carbs and they both had a stranded wire choke 
cable and the knob had a large "C" painted white. Was that the 
correct type of knob and cable or was it perhaps a replacement?

I am interested in finding the knob and cable if that is the correct 
one for a tri-carb but is seems to be unobtainable but I don't know 
if it is correct.

Thank you,
