BEING RELISTED DUE TO A NON PAYING BIDDER!!! - Up for auction this week we have 1 pair of antique Buick hubcaps. I don't know the year I'm guessing 1920's -1930's. I bought these from a famer about 30 years ago who had them in an old shed. They measure approximately 8 inches in outside diameter. The inside part that fits inside the wheel measures 6 1/2 inches in diameter. One is pretty decent but does show a few dings along the edge (see close - up photo). The other one is pushed in and scuffed as if it had been in an accident. They are not perfect, but are very old and cool enough for wall hangers or if you have an old jalopy that is on the rough side.
