NOS Black Road Runner horn verification

[73charger340]

I bought this RR horn years ago and never installed. I was told it was NOS but I wanted to verify with you all to confirm before I put it up for sale. It did not have a decal but I found one on ebay that was said to be NOS also. Here are the pics. It does say sparton on the horn. Also what years used the black horn like this one.?

1968 was black and no decals.

Does the bracket look correct for 68?
