Interesting. Will not argue with that.
A good example of the Chev Superior parts mix up that confuses us all to the point that I doubt anyone knows for sure when some of these differences were introduced, as many seem to overlap. As Alfred Sloan said "our biggest problem all through that era was being able to produce enough of everything" Therefore there may have been several suppliers of these bits made from different materials etc.And of course parts may have been interchanged in the course of the years since.
Fischer bodies? Oops, I had better be quiet. We only had Holden built tourers apart from the rare import.
