Examined closely, chrome has some areas of duller finish, along with some small tarnish specks here and there(see pics). Molding is basically very straight, but a couple of slight wave imperfections in metal present from when part was stamped(on either side of raised elliptical ornamentation at top center)(see close-up pic). Still a neat piece for a driver or un-restored car as-is, or should be a nice one to re-chrome for show. Back side of molding is as clean as front(see back side pics). This part replaces Chevrolet part number 3687150.
As stated, correct for'48 Chevrolet cars, will also work on'47.
