I bought a 71 SuperCourse Frame which had been completely stripped including the headbadge. After powder coating, I bought a NOS badge online and riveted it on with the smallest aluminum rivets I could find. Heres how it looks.
It's a little bit off center, but I think thats because it's not the proper badge for my year bike and I used the existing rivet holes. I wish now I had thought (Like SouthPawBoston) to glue it on.
