The photograph from Brad looks similar to a 1928 Canadian grain truck from the Brantford Body company that was judged at Dearborn a few years ago. I know he had all the aluminum hubcaps restored by a friend of his. To me they looked like they were originally cast. The truck was shown in the MARK magazine with the other fine point vehicles after the Judging. The owner is Everett Hessels in Canada and is a fine point judge and on the committee updating the standards. Everett is a wealth of Canadian Model A knowledge. If you want to connect with him send me a PM and I will pass it on to him.
