LOL. I have a printing from 1986 of TMOST. Kaiser, you can probably find a scan of that on one of the Star Trek blueprint sites. The main differences in that drawing and the build model are variances in position of the hulls. The nacelles are mounted farther out and the secondary hull has more of a curve to it in the forward/middle sections. Also the bevel on the lower edge of the primary hull.
You can see more of the comparison in my other thread about the TOS Enterprise (scroll to middle posts):
