I built all the AMT Star Trek
kits in the '70s, along with the Revell and Monogram kits from the Apollo program.
I thought about buying a second "Enterprise Bridge" kit for parts to complete the circle, but never did. That was a great kit, though.
The Enterprise itself was the only kit I built twice, and that was when the boxes were saying "Build the entire fleet!" -- a slogan that cleverly fired a boy's imagination. I named the second one Lexington and went with the Franz Joseph number for it.
