I have recently managed to acquire one diver's helmet dash lamp albeit black rather than the brown which I require for my PA. And only one rather than the two I need.
I believe that the one I have acquired to be original. However a friend has questioned what shape the cut out should be. Should the ends of the cut out in the cover be square ended or round ended? Were the brown covers and the black covers used on other types of MG the same shape?
A little input form the experts would be much appreciated.
