I don't know if this is the place, but I have a hubcap from my '59 356A Cabriolet. The car is long gone, stolen in L.A. more than 30 years ago, but this hubcap survived. I had put the spare on a few days before, and left the 'cap in my mother's garage. She just sold her house, and the thing came back to me like an old Mexican lunch. God, I love that car. Silver on black, with that incredibly heavy metal hardtop.
It's in good shape. The car had about 20,000 on it when it went to heaven, so it isn't brand new, but it's damned close. The chrome is still good, and the cloissone emblem is in great shape. The biggest dent is on the rim, about 2 mm. It looks like it did in '61.
If you can use it, let me know.
