This is a pair of decent used door sill cover plates from a Volvo P1800. They will fit all 1800 models.
They are in generally good shape, with no excessive bends of dents, and will probably polish us pretty well.
The brown discoloration on the bottoms of these parts is rust stains from the body of the car. The sill plates themselves are aluminum, and the brown will clean off. In any case, it's on the bottom and won't show once they are installed.
