I believe that was the J that was for sale in NW MN about 8 or 9 years ago. I looks like a headlight switch knob was used for a radio knob on it. HJ radio knobs are extremely rare. I always wondered if the knobs Rudy produces for the '49 - '51 Frazer would be good sub? In the photo of the "Last Onslaught" car you posted, it was easy to see the chrome Kaiser radio knobs work well.
