I don't have a picture of my dial (it is in pieces), but I found this picture on the internet
and is identical to mine.

As I said earlier, the same basic knob was used for many years, later versions were
black & silver or plain black. The portable models say Dishmobile on the front of the
knob.
If any of you see one or a junked machine in your travels, it would be greatly
appreciated.
