Here are some pictures
Unfortunately, I do not have an original Ford Accessory lighter. I do have some similar ones. The first picture shows a generic steering column mounted lighter. The second shows a NOS in the box generic lighter which can be mounted many places. Like the Ford supplied lighters these are both made by the Casco lighter company, model 600. The head on the Ford supplied lighter knob is similar to the one in the second picture, it has flutes on the side of knob. However the one in the picture is brown whereas the Ford supplied one was black. Also the knob in the second picture is just a bit wider at the top than the Ford version.
