Morris Minor Owners Club

I am trying to work out what the colour of the trafficator arm covers should be on my 1960 black 2 door. I have looked at Ray Newell's 'Original Morris Minor' book and while some seem to be coloured the same as the body, some are polished chrome. Does anybody know...?

Early cars (MM and some Series11) often had body colour covers but every Minor 1000 I've ever owned or seen along with every 4door Series 11 has had stainless steel ones. None were chromed. So I reckon stainless steel is the answer.

Many thanks. Stainless it is!
