Do we really know how the scales compare?
According to www.ex-astris-scientia.org
, the K-7 is 450m and the Constitution Class ships are 289m. This confirms how out of scale the K-7 kit's 1701 was. It makes me wonder if AMT was hoping for a literal recreation of the scene as one would see it in "The Trouble with Tribbles,"
where the 1701 seems that small in the background.
The 6-inch long Enterprise as part of AMT's mid-70's Space Ship Set
would have been a better scale fit for the K-7. I wonder of anyone ever tried to match the kits back in the day.
