My apologies to Cary L. Brown
. I did not mean to minimize your interest. It's just that for the moment I was posting a response I forgot who it was that was interested in rendering my version of the TOS shuttlecraft.
The external differences between the fullsize mockup of the shuttlecraft seen onscreen and my drawings are very
subtle and they were meant to be. The most obvious difference is that the fullsize mockup had an exaggerated pitched forward stance that emphasized a forced perspective appearance onscreen when viewed from a side or rear angle. My version moderated that pitched forward look by making the lower line of the stabilizer rim parallel with the nacelle centerlines while maintaining the wedged shape of the craft.
