Hi it’s part my Fiat 500 D collection. I happen to find this in an old Fiat garage, it’s original. Its not for sale. Send a picture of yours. Mine is in great condition no rust at all. I just sprayed.
I didn't spot that yours was "D" but you'll know that this is an "F". Obviously I added the front wing. Your reverse side is much more detailed. Mine is also rust-free apart from the surface. I'm planning to spray it to exterior quality and use it as a wall ornament.
True..very rare, but having said that, a year after paying a slightly eye-watering price for it from Italy, one turned up on eBay UK for around £100 and didn't sell on the listing.
