Your pics are a little dark (the white background makes the camera do that), but they look like early replacements in less than ideal shape. With that said, I suspect that is the type of "original" we will find on most cars that have old stock wiring.
This pic shows a difference in tracer types. All the Ford dash and generator wiring I've seen had the closely spaced "double spiral tracer" while replacements have either a single spiral tracer or a double spiral with a clear gap or space between them. I'm suspect either type would be accepted in judging but condition is important.
I'll take better picture's this weekend .I'll take a picture of a orginial n.o.s. wire harness too or maybe early replacement .Still i will not use them.
