Does anybody Know from which car it is? it seems to be made by a company called Antisol from Argentina
That's an adjustable width visor, universal type fit for cars and trucks from the late 30's to the early 50's with a split windshield. It's an aftermarket accessory, very similar to the Fulton Sunshield made here in the USA. Very neat piece, would look nice on a restored stocker or a lowrider bomb.
