I have a 40 spoke wire wheel ,16 inch ,5 on 5 1/2 bolt pattern , 6 inch wide overall, 4 3/4 bead to bead. It is Marked Motorwheel Corp , Lancing Mich. Has a number of : L 6 over 450 --- like a fraction. I have no real knowledge of what car it is from. I was told that some Prewar Buicks might have had that bolt pattern & had 40 spoke wheels. Any help to identify it would be most appreciated, I need another like it & knowing what to ask for should make it easier to find. Thanks , Dave
