I hear ya on the secondary hull. Ever since they put the Matt Jefferies drawing on the AMT model kit box people have been putting extra curves in that secondary. :lol
The actual hull is, as you say, mostly a straight tapered cylinder.

I just looked at those plans more closely and they are really close. They are the best Karl on the net. He's just got a slight curve in the secondary hull that should just be straight. So for those of you looking to build a TOS E these plans would be the best to use and that coupled with the pictures I put a link up to here would get you there.
