The air cleaner cover for my 67 L71 has been confirmed during a Top Flight judging to be an original cover. However the air filter instructions appear to be embossed not silk screened. The surface is not smooth as the characters are raised. From what I've read this is not discussed in the 7th edition judging guide. Only silkscreen. As you can see in the picture I've attached there is black showing in some areas. I assume this is because some of the plating has worn off. Hopefully someone can shed some light on this. Thank you.
