I wonder why the outside skin on the upper stage did not cover the lower fin section ?

Regarding drawing 600-00389 (Dave's first attachment), I believe that drawing has an error in the depiction of the taper line that starts at the tip at STA 208.75. As that line reaches the root, it lands at a location forward of the fin can joint, and forward of the forward edge of the fin foot. I've not seen any BBVB/C fin with that feature; all of them have that taper line landing in line with the forward edge of the fin foot at the root.
