1967 Broadcast sheet steering wheel code.

In the steering wheel box on my broadcast sheet it has 12K. Can anyone decode it? I believe the K is for color. My interior is copper/ Thanks

I can't find anything on 12k.. Steering code should start with "S"....HH-1 is Dark copper Poly....#22569...TT-1 Medium Copper Poly #22706

At the bottom of the broadcast sheet is build codes. In the steering column block mine says 13K. The next block is steering wheel and horn ring. It says 12K.
