What is the name of the side stainless that loops the windows and looks to be held on by clips on the 41-48 Mercury's and maybe Fords? Were they common? Were they an option? What about the rain gutter trim? Common? Option? Were they all the same as I have seen some that have grooves in the trim? I thought it might be 1941 on the grooved as it kind of looks like the side trim. Any help would be greatly appreciated Thanks Paul Picture is from the net of cars with the trim.
