Side stripes

Has anyone seen side stripes like these before? They're kind of like aar style stripes but they stay the same size the whole way down the side of the car. They are painted on. Curious if there is a stencil or anything to use to recreate them. I am gonna start sanding the car down for rust repair soon. I love the way they look and want to keep them. Also does anyone what color this is? This is an old repaint it was originally a white "spirit of 76" car. IMG_20191005_164531486.jpg IMG_20191005_164549656.jpg IMG_20191005_181942654.jpg
