Most interesting. As far as I know, there was not a color option for the wood in the 113. As has been mentioned in other posts, the best gauge for judging the wood color is to look at the trim in the rear window of the hardtop. Because of its location it does not get the sun exposure that the dash wood does.
I know others have posted photos of various numbers written in marker crayon, inside the headlight buckets, on the door panel cardboard, on the seat backs, etc. But even these did not seem to correlate with anything on the data cards or code lists.
Will be most curious to see what others have to type.
